The cliffhanger should have been "YES", agh... I'm expecting a huge let down in the next episode. He would either cuck himself again like Season 1 finale in the anime, or someone else might step in like Mami, Ruka or his best friend. No matter who, that character will earn the hate of everyone.
Gosh, I wish I'm wrong ffs.
Real talk, the setting is leading Kazuya to take a cliché MC decision and step back because she's doing this kind of question while she's drunk. Or... he'll give some kind of weird answer like she did to her partner of the theater, like "I can't say I don't have feelings for you" or something like that.
