Well this is going to get Ugly, NTR here we come? is Ueno notices or know, he going full to the dark side i.e. the bully Trio, that's good for Chiaki, but Tsubomi is the best option (?)
Took a peek at raws and this is gonna be the most cursed trip ever not only is her ex boyfriend there somehow the bully trio is there too. At least if Uneo does get NTR’d(which is likely because this is published in young mag) he can get comforted by the lesbian’s tits.
Yeah this might be worse in some ways than the chick from "GE: Good Ending", at least that one wasn't masturbating to her old crush and wasn't trying to use the MC to move on (tho a single call from senpai was all it took to forget about the MC)
