Sensei

Hayami Kagura (pen name Hasune) is a character who appears in the first chapter of the second volume. He was initially assumed (by Chisato) to be the arts teacher at Riju and Shunsuke's school, but turns out to be a famous illustrator. He is first seen saving Chisato when Chisato is about to slip, fall and injure himself on a rain-soaked, slippery street outside Riju's school. Chisato thanks him, then panics upon noticing that a painting Kagura had been carrying has gotten wet. Kagura, however, reassures him and says that he will just paint another one.

Chisato still feels guilty for accidentally ruining Kagura’s painting, but before he can think further on the matter, Kagura suddenly embraces him and murmurs that Chisato reminds him of someone he used to know. Chisato is bewildered, but then Shunsuke suddenly appears and proceeds to argue with Chisato, furious that Chisato has no time to meet with him (Shunsuke) but seems to have time to meet Kagura. The argument ends with Chisato and Kagura walking away together. Chisato then takes a shower at Kagura’s place and Kagura asks him to be a nude model. Chisato declines but they stay in touch.

A few chapters later, Kagura was revealed to be the illustrator of the Mizuki series. Shunsuke dislikes him to some extent due to being jealous over Chisato’s professional admiration of him.

Some time later, Chisato visits Kagura’s house to discuss some work issues. Kagura revealed that The reason he approached Chisato was because he looks like someone whom Hayami was in love with 20 years ago, for whom he regrets not confessing his love. He then expresses romantic interest in Chisato, saying that he won’t let him go and Chisato should become his. But while embracing, they are interrupted by an enraged Shunsuke.

Shunsuke and Chisato reconcile with each other shortly after, and then Chisato gets a phone call from Kagura who says that he would like to illustrate Chisato’s own novels.
