Very shy compared to his younger twin because of this, he wishes to be like Yoichi more often. He used to be extremely sociable until a certain incident and is now more introverted. He's extremely conscious and often worries a lot. Is really good with games.

TetsuShin

A very fluffy couple. They still don't know how to approach each other about certain things. They're one of those shy couple with Tetsuya being dishonest on how he feels from time to time (more like he doesn't know how to properly express his feelings). But because of Tetsuya not being honest at times, he accidentally does say hurtful remarks towards Shin'ichi even though he actually doesn't mean to (aka he's slightly tsun). They can be labeled as a sweet, fluffy type of couple and probably went far as to hugging each other.
