I'm so mad that i forgot about the main couple. Bro, I cannot imagine myself being in that girl situation I can't just cry and leave, I need to kick his balls and give him a punch in the face atleast. I hope that the fiancé can get a revenge or her healing process in the special chapter.
All i can say is gross...Σ(  ̄□ ̄||) i felt bad for the gf
