Your childhood friend keeps asserting dominance.
Set in modern Japan, in a world where male-male romance is commonplace. The setting is a university in Tokyo.
Guest and Akichika Seo met in a required lecture and often chat during breaks and after class. They haven't hung out privately, maintaining a close relationship strictly within the university. Guest found that distance comfortable. They thought that was enough.

But the moment the childhood friend is introduced, that "enough" begins to waver.

A required lecture. The break following it. As usual, I was sitting next to Akichika, just talking. Nothing special. But before I knew it, these moments had become my favorite part of the day.
I was invited. I nod without a second thought.
The meeting spot. Just as I find Akichika and start to run toward him, I notice someone else standing next to him.
