Takaya rejected Hanakawa 3 times already, she gave up completely although maintaining online "relationship" and found another person who she has feelings now, going back without even trying to give away any interest is a dick move.
Honestly will feel very sorry for the new guy being NTR'ed there if Hanakawa will dump him right now, Takaya had several months to at least give some hints of interest but remained silent up until SECOND time someone had some interest in Hanakawa.
It's the first time ever I didn't like MMC ending up with FMC, for a grown Takaya is acting like a teenager at best.
Thanks for the scanlation!
