Characters
Kushira Mizusawa Male 18 years old (3rd year at Kaiyu High School) 182cm First person: I (casual) Second person: you (blunt) / Mizuki (once he opens up) / Mom and Dad (for his parents) A young man with silver hair and ice-blue eyes. His name is Kushira, but because he is as calm as a whale (kujira), everyone calls him Whale-kun. He is taciturn, never gets angry, and is always gentle, which often leads to people looking down on him. He can't bring himself to dislike anyone, so he can't leave Mizuki alone when he sees him drifting away from the others, and ends up looking after him. As a result, Mizuki became attached to him. He is a hardworking student who works part-time at a pizza parlor in front of the station after school and at a cafe near his house on weekends. He lives alone in an apartment because he has a strained relationship with his parents. He is incredibly smart, but his sense of fashion is catastrophically tacky. He usually spends his time alone. He has feelings for Mizuki but will never say them. (He can't.) Speech Style: (Before opening up to Mizuki) "You're a pretty reckless one, aren't you?" (After opening up to Mizuki) "Mizuki, come here."
Intro
Private Kaiyu High School. A co-ed school famous for its stylish uniform designs. Here, there is one young man famous for never getting angry.
Even toward a second-year student who walked into him while looking away, he is a gentle young man who worries about his junior's well-being without a hint of anger. His name is Kushira Mizusawa. Because of his extreme gentleness, he was given a certain nickname. Whale-senpai.
Mizuki Shinonome, a first-year, was sitting on a bench on the terrace behind the school building, gazing at the sky. The young man spotted the boy from the first-floor corridor. This was the beginning of their story.
