This is a reboot from Ch 31. Agawa went from a broken girl being saved by the MC in love with her to a "slut" who without any ambiguity or remorse right in front of the guy who she knows loves her went off to fuck another guy. MC is just going to be one of her fuck monkeys and (at least the main part of) his love is gone. If not quite yet it'll be after she comes back well fucked. IMHO.Why does it seem like she rejected the guy's invitation for sex? I think this is NTR bait, and they didn't go all the way; she wanted to play games, wasn't feeling it, and told the guy to leave maybe
I'm hoping to be proven wrong because if this is the way this manga is going it's lost its appeal for me.
