Damn, not sure how I feel about this development. Each of the girls kinda had this coming in their own right. Except maybe Akito, but she did go on the date with the f boy, even if nothing ended up happening she still did so after getting caught up in his bs.
SM girl really only went along with MC after her own crush on f boy didnt work out so shes doubling down on that sense of "I fixed him, so he belongs to me now" feeling. Believing she got one up on main girl.
Speaking of Agawa, she deserves this the most as it brings it full circle to the first ch. On top of the fact that shes been fooling around with that one chick because she is unwilling to admit her feelings for mc. Which is hurting that chick and mc both.
Pres I think honestly is just enjoying watching the little s*x pest she helped create grow into a full blown f boy. So it doesn't hurt her exactly, as it at least doesnt seem like she has romantic feelings for mc.
All that to say, this story is wack.
