Ikr? I'm pretty confused too, but here's my theory, if you don't mind.
I can't remember the names, so i will calk them:
Seme - mc who lives with the cat
Uke - seme ex who already dead
Bbf - guy who comes to seme house
And woman - the bitch on the last page
Ahem. So.. maybe, yeah maybe.. in the past seme going out with uke, but seme had something going on with that woman (idk maybe seme cheated or smth) then woman did smth to make uke upset, so he died (idk whether suicide or accident). And so, knowing uke dead seme depressed couldn't forget about him.
And when bbf working with that woman (not in korea), she blabbering that it was her fault, so maybe bbf killed her on the last page.
Maybe, yeah maybe ╮(￣▽￣)╭
Ok...the confusion started a few chaters ago but now Ibreally do not understand the whole story at all! Who is who now and what is going on here!?!?!?!?
Does anyone care to explain everything to me!?!? Pretty pleas!(⊙…⊙ )
