Man, I’m so glad I’m done with this one, it frustrated me for several reasons lol
Anywhere, here we have Einon (17yo) and Serodio (23yo), they’re brothers. Serodio owns a casino in which Einon works as a bartender. Serodio is pretty cold most of the time while Einon usually puts up a cute act. In reality he’s very confident though and likes to get others drunk for…yaoi reasons.
