I'm confused (and going back, re-reading is such a chore!)
Isn't Yahwi the one who bit Jooin (*both* times, right?)
Why does Yahwi think Cain did it/ not remember *he* did it?
--Drunk memory loss?
...or am I getting mixed up with some other story???
(Yes, Yahwi is hot & has a sad backstory, but he's a total ass most of the time...)
Yahwi & Jooin knew each other as little kids, but Jooin doesn't remember?
jooin was sick and cain helped him with the medicine and then he got carried away and kissed him while leaving that mark on his lips, yahwi saw that and understood what was going on and got jealous af like a little kid so he forcefully kissed jooin and bit him exactly on the mark cain previously left because idk, possessive shit ??
I can't recall which manga/manhua/webtoon/etc. I was reading at the time, but among the closing credits for one of the chapters there was a picture (I can only assume) was a (massive!) *spoiler* for this story...
(--The pic I'm referring to DID NOT appear to be *fanart*)
While we haven't seen much indication of it (aside from Cain's occasionally odd statements and behavior), one of the genres listed for "Yours to Claim" IS *Supernatural*
