Summer Boy Blue

I was the one who ruined our friendship—

Jun and Michiru drifted apart after their parents accidentally caught them having sex. By chance, they meet again in the spring at seventeen. Just when Michiru thinks he might finally be able to forget everything Jun stops him as he desperately tries to run away, using the same words he had once said. Unable to resist, Michiru finds himself drawn back into Jun, and before he knows it, he is once again caught in a relationship he cannot easily escape. But differences in their backgrounds and lingering trauma slowly begin to weigh heavily on his chest.

"I shouldn't intrude on your life any further."

Even as Michiru decides this will be the last time, Jun has no intention of letting him go—

A story of restless adolescence and rekindled first love. A fresh, coming-of-age BL depicting the second puberty of the heart.
