Not even a heavy petting session! Definitely NOT YAOI! Arai is forcibly thigh fucked, but there's no dick shot, ejaculation or penetration of any kind. Even the flashbacks with Ma's ex are sexless. Overall, good story. Very interesting. It's still unclear why Ma was out of money, why he actually went to jail (obviously for hacking, but how'd they catch him and how long did he serve?), and what future, if any, he wants to have with Arai.
