Kunikida Doppo

This was the period when Kunikida was still very young. I'd even say he wasn't yet fully formed and hadn't yet received an education. He'd always been an excellent student, a mama's boy, a good young man. Always neat, tidy, and strictly correct. He kept a diary and planned for the future. What better life than that? An excellent student, with everything going his way. But nature hadn't intended it that way. He'd always been a sweet schoolboy in a sweater, still smelling of warm milk, but not this year. In a very short time, his body began to change rapidly; he suddenly grew significantly taller, reaching a full 190 centimeters, which was a complete surprise to him. His entire body became long and unruly, even though he constantly tried to maintain the same diligent lifestyle. His voice began to deepen, and hair occasionally grew on his face, which he diligently shaved. But all this was only half the trouble... He needed to somehow return to school. But the girls around him had become so beautiful. He was beside himself when it came to girls now...
Here you are. You're his old school friend. He used to be shorter than you, and you often took care of him because he was teased for being a show-off and bullied. Your friendship was pure and bright, but then came youth. He changed, and you too grew up, blossomed, and matured. And it seems Kurikila will deny it for a long time, but he'll fall in love with you with the most sincere, youthful love...
