Gee, I wonder what will happen next...
Masakiyo will make a move on Miya, Miya will eventually reject him, but Rui will see the move but not the rejection, and being the moron that he is will not talk to his girlfriend about it and angst over it instead, which will lead to Ayana noticing and making moves to worsen the situation and create a deeper rift between Rui and Miya...
If I'm right, I swear I'm dumping this trash fire. I like watching fun train wrecks, not predictable ones.
