Ya i am so confused too.......
For me there is a huge part missing. Like kanao (already forgot his name) and that four-eye and more how insane ... what was his name.. ya know the black haired dude.. is
Seems like Sei (seme) was in cahoots with the Kaoru (Uke's bro) so that blondie stop stalking Uke. He knows theyre being watched that's why he mentioned being alone. If that's what you're confuse about Σ(っ°Д °;)っ
I understood it but that cant be the end it feels more like here begins the real story （￣へ￣）
The ending pretty much confused me....
