"May I...approach you?” Mizuki and Hoshina have been good friends since kindergarten. For Mizuki, Hoshina is his favorite and irreplaceable childhood friend. But now that he is in high school, his “love” for Hoshina is changing color. Just by being next to him, just by looking at his body, I have a hot feeling in my heart and I don't know what it is, but it's a dangerous feeling. I wonder what this feeling is... I'm not sure if it's the same thing or not, but I'm sure it's the same thing. The story is about a monopolistic, strong, face-chested, can't-quite-quite-quarter guy and a single-minded, loose high school student who doesn't know what “love” is. A Certain Childhood Friend's Pure Love Story
