Senzaki Yu in Episode 15/16.
Who plays him? I feel like I've watched him in a drama before but I can't find out who plays him anywhere.
shareWas wondering this myself and spent half an hour looking up photos of all the cast listed in the end credits. He's played by Yasuyuki Sakurai I believe, can't find anything else he's done. Too bad, he played a creeper pretty well...
Edit: I take that back, IMDb says he was in The tv show Piece, he played Mizuki
