Gin's manga / #age difference(2)

Mio Keisuke is a high-schooler who leads a rather dull, boring life. He can't keep a girlfriend because being a kept man's too much of a hassle, and he can't bring himself to fall in love and want to please his woman. Then one day he seeks shelter from a sudden downpour under the awning of an apartment owned by Yugi Kakeru, and suddenly his life isn't so dull anymore as he finds himself falling for his aloof and yet obviously lonely friend.

This story is about a relationship between a teacher and his student, Homura. It just so happens that Homura's older sister, Kaori was the teacher's first girlfriend. Back then, the teacher would always use Homura as an excuse to run away whenever something happened, and he would never get in the "mood" whenever he was with Kaori. One day, while going through the exam papers, he noticed that Homura wrote "I like you, sensei" in a corner. Will he accept Homura's confession?
