## Summary

Every morning Taiki Inomata arrives at his school to see his senior Chinatsu Kano. When he arrives he is accidentally hit in the face by a basketball. Chinatsu apologizes to him, handing him a candy bar. Taiki recounts how when he comes to the gymnasium to practice for the badminton team in the morning, Chinatsu is always there first no matter how early he is. He notes she's always the first to arrive to diligently practice her shots for the basketball team, which is something that made him love her.

When Taiki admits to his badminton friend Kyo Kasahara he'd love to marry Chinatsu, Kyo tells him how it would not happen due to Chinatsu being popular and talented whilst Taiki is unknown, putting them in two completely different classes. Taiki says despite their differences he's still going to make an effort, and Kyo suggests for him to work in stages, like getting to know her name and number. Hina Chono, a friend of theirs from the rhythmic gymnastics team, sneaks up on them to ask what they're talking about. Taiki asks her about what a girl wants in a guy. She's excited to hear this, talking about being comfortable, dependable, and a hunk. The boys leave, disappointed.

The next day on the way to the gymnasium, Taiki sees Chinatsu outside waiting for it to open. As he figures out a way to approach her, he notices her sniffles, which causes him to immediately jump at the chance to offer various things to warm her up from his bag. He soon realizes how ridiculously he's acting; but it amuses Chinatsu, who jokingly wonders what else he has in that bag. She appreciates his efforts, but assures that she's alright as she wraps his scarf around him. The gymnasium opens and she wishes Taiki well with by his full name. He's initially shocked about how she knows his name until she reveals she read it off the label on his scarf which his mom wrote.

Taiki practices hard at badminton, motivated by Chinatsu saying his name. He notices her chatting to the coach of the girls' basketball team outside when Hina comes by. He mentions that he's aiming too high with Chinatsu and teases him, saying she saw her walking alone with another guy, before leaving.

After changing, Taiki notices that he forgot his towel and heads to the gymnasium where he sees Chinatsu still practicing. She offers to play a game of one-on-one with him, which leads to his immediate fatigue. He recounts how his mother used to be on the basketball team, so he's used to playing. Chinatsu mentions that her mother also played on the basketball team. She asks Taiki if he'd considered playing on the basketball team, but Taiki says he prefers to be alone and take all responsibility onto himself. He tells her about a time a year and a half ago where he saw her crying whilst practicing, due to her team barely missing nationals, which ended up motivating him. She is shocked from hearing that, stating that she had forgotten about it. As it's time to leave, they pack everything away, accidentally touching fingers; Taiki mentions that she feels a lot warmer than when he spoke to her earlier.

At home, Taiki spots Chinatsu's image in a magazine. His mother mentions how she was on the basketball team with her mother. She also reveals to him that Chinatsu's family will be moving overseas; he is shocked by the news, running to the school. He meets Chinatsu at the gymnasium, telling her she has to make it to nationals and talks about how much she motivates him to work harder. He tells her to never give up, hating how moving abroad would ruin this for her; but she interrupts him, reassuring him that she isn't moving with her family and would be staying at a family friend's house. She tells him how he reminded her of her pain from missing nationals, which made her unwilling to give up. She thanks him and asks to play more basketball with him, as well as badminton.

The next day, Taiki wakes up realizing how embarrassing he was the day before, realizing that it's the first day he doesn't want to see Chinatsu. He enters the kitchen only to be met by Chinatsu. Their mothers come in and announce that she will be living there since they're going abroad as ex-teammates. Taiki is shocked to realize he'll be living with his school crush.
