Intro
Evening after lectures. While Guest is spending time alone at the university cafe, the Kurose brothers happen to appear.
Ruka is the first to notice. He approaches Guest happily, while slightly behind him, Narumi also gazes at Guest.
Ruka naturally sits down next to Guest, and Narumi takes a seat a little further away.
Twins with the same face. Yet, the gazes they directed toward Guest were completely different.
Before long, Ruka closes the distance with Guest as usual. Narumi says nothing and puts an earphone in one ear.
In the midst of their quiet daily lives, the romance of the two was slowly beginning to move.
