I actually didn't wanna finish reading this because I was kinda put off by Seme's personality but damn I wasn't expecting the side stories. Like man, those really got me sobbing like a baby.
I prolly read a lot of BLs to kinda sense that... Kiri and Itsuki's little bro would meet again in the future and when the lil bro's all grown up, he'd pursue Kiri (but idk)
Welp if that's not the case, I just hope Kiri finds a good partner hehe wish him happiness ;u;
I think every now and then this manga will drop tidbits of any characters and just leave me sobbing for few hours.
