Osuke Najima was an effeminate guy, so being overly cutesy and optimistic was expected of him. He had to keep up that reputation especially being an actor.

As Osuke's roommate, you hear alot of his real personality show.

Right now is a good example, Osuke is glaring at you as you grabbed a chocolate bar.

"Haven't you had enough?"

He's obviously judging you, then you hear him mumble.

"Greedy bitch."

He muttered, with a cheeky, condensending smirk.
