Miller is in Kai’s kitchen, frustrated after hours of baking have produced four failed recipes. When Kai arrives home and a burnt garnish pushes her to despair, he surprises her with a hug and makes her laugh. She explains she’s a contract pastry chef who fixes dessert programs for high-end restaurants and is slated for the cover of Food & Wine and that she took the summer off after setbacks in Miami. When she asks about his parents, he deflects. Kai becomes alarmed when he learns that Miller has been living in her van in Monty’s downtown parking garage. She refuses when he offers his guest room but accepts his side yard with hookups. They clean the kitchen together.

One week later, Miller rides with Monty to the airport for a road trip. She exchanges flirty texts with Kai and, at the terminal, spots him with Max. Max greets her enthusiastically. On the plane, a player calls her “Hot Nanny,” which Kai objects to. She meets Kennedy, the team trainer. Several players compete for Miller to sit with them, but Kai possessively pulls her into his row. When Kai tries to encourage Max’s first steps, Max falls and cries. Kai soothes him expertly, and Miller is moved watching him as a father.

After a game in Houston, Kai goes to the hotel rooftop pool late at night and finds Miller there. He asks her to stay, and they flirt and swim. She asks about Max’s mother, and Kai explains Ashley was a casual relationship who reappeared a year later with their six-month-old son, having decided she didn’t want to be a mother. He expresses anger at missing those first months and fear of missing more. When Miller nearly slips under in the deep end, Kai pulls her close, and she wraps her legs around his waist. 

She correctly guesses that he fires nannies and wants to quit baseball because he fears missing milestones in Max’s development. Kai reveals his parents were absent for his childhood achievements and that his mother died in a car accident. Miller shares that her mother died young of cancer and that Monty is her adoptive father. He was her mother’s boyfriend for only a year but adopted Miller when she was five at her mother’s request and quit professional baseball to raise her. She urges Kai not to retire so Max won’t carry the guilt she does and offers to help him find balance in his life. A security guard interrupts their conversation to remind them that the pool is closed. Kai playfully accuses Miller of getting him in trouble. Laughing, she says she plans to get him in much more trouble.

Kai confronts Monty for advising him not to retire when Monty quit baseball to raise Miller. Monty explains their situations differ and says that he was less talented, older, and had no support. He knows Kai is looking for an excuse to quit. Monty doesn’t regret his choice, but he encourages Kai to enjoy his career, noting that seeing a parent fulfill their dreams makes a child proud. He encourages Kai to rely more on his support system, which includes his brother, the team, and Monty himself. Before leaving, Kai thanks Monty for taking care of Miller.

On the field, Miller shouts a compliment about how Kai looks in his uniform while holding Max, who is wearing a miniature matching jersey. She arranged seats beside the bullpen so Kai can see them during the game. Isaiah takes Max onto the field, and the team gathers around him. Watching, Kai feels for the first time that he can have it all. Miller places her hand on his, and they share a quiet moment. He thanks her and calls her “Mills” for the first time. Then he teases about wanting to see her in his jersey and then take it off.

After the game, Isaiah pesters Kennedy, who promises to work on him properly next time after realizing he’s genuinely hurting. When the team announces they’re going out, Miller looks to Kai. He implies he’s staying in, so she declines. Not wanting her to miss out, Kai encourages her to go, but Travis’s enthusiasm sparks his jealousy. Monty intervenes and offers to watch Max so Kai can join them, reminding Kai to seek a better work-life balance. Miller encourages him to join them, and, feeling guilt-free, Kai agrees.

Kai waits in the hotel lobby, wrestling between his attraction to Miller and his belief that she’s off-limits. Isaiah gives him a beer and teases him, noting that Kai only agreed to come out with the team after Travis invited Miller. When Kai asks if Travis is interested in her, Isaiah asks if it would bother him. Kai lies and claims his only concern is work. Isaiah calls him out, saying he’s seen how Kai looks at her. Isaiah gives him a pep talk, reminding him of his past confidence and pointing out that being a father is a bonus, not a liability. 

Miller appears, and Kai inwardly admires her tight jeans and red lipstick. Travis intercepts her and offers her a beer, confirming his interest. As the team heads out, Kai and Miller hang back in the empty lobby and exchange compliments. Miller asks about Max, which surprises Kai given it’s her night off. At the door, Kai stops her, trapping her against it, and whispers that he thinks she’s hot and can’t keep his eyes off her. Miller retorts that knowing she irritates him is more satisfying than knowing she attracts him. Kai admits she’s excellent at both.

The team informs Miller of their plan to make Kai jealous. At a country bar in Dallas, Kai places a possessive hand on Miller’s hip. Travis sits next to her as part of the team’s plan. The group does shots of cinnamon whiskey. When Kai wipes a drop from Miller’s lip, she makes a suggestive comment. He asks if she’s flirting, and she confirms she has been since they met. Isaiah asks Miller to dance and explains that the players will take turns dancing with her to force Kai to express his desire. Miller agrees, finding jealous Kai attractive. She dances with six players while Kai watches from the bar. 

When the music slows and Travis pulls her in, Kai finally leaves the bar but heads to Isaiah’s table instead of intervening. The group notices Dean Cartwright, a rival player, has arrived. They explain Kai fought Dean last season. After Dean injured Travis with a dirty slide, Kai retaliated by hitting him with a pitch and then punching him when he charged the mound. Kai approaches Miller at the bar, and they banter about his jealousy over Travis. He admits she might be his limit before pulling back when Travis returns with drinks. On the dance floor, Dean puts his arms around Miller and insists that she dance with him. Dean reveals he slept with Isaiah’s high school girlfriends to sabotage his performance during baseball games. When Dean’s hand drops to Miller’s backside, Kai appears, shoves his chest, and orders him to remove his hands from her.

Kai has been fighting the urge to intervene all night, telling himself he cannot be the man Miller would want. When he sees her in Dean’s arms, he’s consumed with rage and heads toward them despite Isaiah’s warning. When Dean’s hand drops to her backside, Kai shoves him. Dean taunts him, calling him an absentee father and asking if he’s looking for a new mother for Max. When Dean mocks him for being infatuated with his coach’s daughter, Kai deflects by saying she’s just the nanny and immediately regrets it. He turns to find Miller gone. 

Kai chases Miller downstairs, where she yells that she can take care of herself and accuses him of ignoring her all night only to make a scene. In the stairwell, she confronts him for his hurtful comment. Kai apologizes, explaining he hated seeing Dean touch her because Dean is disreputable. Miller argues she doesn’t need his permission. Kai pins her against the wall and declares she’s his problem. When she challenges him to do something about it, he kisses her passionately. He lifts her so her legs wrap around his waist, kisses her neck and collarbone, and says she tastes sweet. Miller whispers that she’s leaving soon. Understanding this as an out if he can’t handle a casual relationship, Kai sets her down and says he needs to check on Max.

The elevator ride back to their hotel rooms is silent and tense. Miller understands her reminder about leaving was necessary because Kai tends to get attached and she doesn’t. At their doors, Kai offers a stilted good night. Later, he knocks on the adjoining door and explains Monty has fallen asleep in his bed next to Max’s crib. After she makes him ask directly, Kai requests to sleep in her bed. They get in, and the awareness of their kiss and state of undress makes the silence charged. 

Miller asks if Kai’s father knows he’s in Texas. After a long pause, Kai reveals his father doesn’t even know Max exists. He developed an alcohol addiction after Kai’s mother died and abandoned Kai and Isaiah when Kai was 15. Kai says he’s not angry anymore but misses the family unit they had, which he’s trying to recreate for Max. He considered telling his father about Max but decided against it because Monty had already earned the grandfather role. He thanks Miller for listening, admitting he’s never told anyone before.

Kai changes the subject to her work, saying he researched her online and is impressed. Miller explains her creative block stems from the pressure of a high-end career where food is analyzed rather than enjoyed. He asks why she doesn’t open the simple bakery she once dreamed of. She admits her current career is more impressive, internally acknowledging it’s for Monty’s benefit. Kai asks her to bake for him and admits he wants to kiss her again, but he says they can’t because it will lead to sex. He no longer does casual relationships since becoming a father because he can’t risk himself or Max getting attached to someone who’s leaving. Miller accepts this, but Kai suggests they cuddle instead. Surprised to learn she’s never cuddled with a man, he playfully chases her across the bed until she agrees. She settles her head on his chest. Kai mentions he hasn’t been with a woman since he learned he was a father and thanks her for bringing Max to the game. As he falls asleep, he murmurs that their remaining six weeks together “can all be good days” (149).
