I don't know what Kei's plan is, but I feel some NTR incoming. It also seems like Yo is in complete denial that he's attracted to Kei. Yep, everything's going all according to keikaku.
I think most of us owe Koto an apology. All this time we were thinking she was a rotten girl who was using Kousuke, but it turns out she genuinely loved him.
@Podi125 MC completely neglects to check how much affection points he has with a girl. Yurea is constantly getting jealous and flustered around the MC and he never stops and says, "Hey, maybe I should check how much AP I have with Yurea so I don't screw myself..." Something tragic is coming.
MC building affection points with the most dangerous girls in the game. Didn't the game itself warn him about that? Something like they'll follow him to the real world if his affection points get over a certain level? I forgot, this manga doesn't get updated that often.
Some of us see the train coming and yet we remain on the tracks.
If you thought this was going to have a happy ending, you clearly haven't been paying attention.
