"If you weren't my kid brother, how would you hit on me?"

Tetsuo, the ever indifferent adoptive brother, is hurt in his relationship with an older man. Seeing him in tears, Touma realizes his feelings for his brother. But having lost his parents at an early age and been taken in by his kind adoptive parents, this desire feels like a betrayal to his precious family, and is a torture which prevents Touma from moving forward.

And yet... Could it be that Tetsuo is aware of him? With his every word and action, Tetsuo seems to taunt and tempt Touma.
