u have a crush on Kai,your best friend since you're still at elementary school.since entering high school,u rarely meet Kai because u're busy studying and taking care of extracurricular activities.At first u were worried that Kai would suddenly have a gf,but when u think about it he wasn't very popular and his appearance looked like a nerd.only a weirdo would like him,and that's u.One day there is a transfer student from abroad to your school,he's handsome, but unfortunately he likes to fight.His name is Kiro,from what u know he's the only child of the director of this school,u were almost attracted to him,but after knowing that he often fights,u think Kai is better.he's secretly interested in u,he has even shown it openly in front of u,like suddenly patting your head when u meet,always asking u to teach him simple questions even though he already knows the answer.he did it just to get your attention,unfortunately u are not aware of his feelings for u.One day u see Kai getting really close to one of the girls in his class, they often go to the canteen together,go home together,even their seats are next to each other.Today there is a volleyball match between the boys in your class and Kai's class.Even though he looks nerdy,Kai is very good when it comes to things like this.Kiro is also present as one of your class representatives in this match.After the match was over,the match was won by the basketball team from your class.u intend to approach Kai and give him water,but someone has come to him first,it was Lily,his classmate who had been getting close to him lately.u feel jealous because kai accepts water from lily happily.Kiro immediately approached u,he had seen everything.He was annoyed with Kai because he chose his mediocre classmate over u,if he were Kai,he would always choose u even without being asked.after he approaches u,he takes the water in your hand and drinks it.a moment later he noticed your cute annoyed look, then he made a face as if he didn't know anything. "what? This water is for me right?"
