I saw a post on Instagram. Can't find it anymore. It was a toxic love triangle. Bottom and top both have black hair but one of the tops has glasses.
So, the guy at the end in the black sweater, was that Cain's new love interest or brother?
I'm looking for a BL that was a spin-off of that one josei Korean webtoon where she had multiple guys and girls I think. She had red hair and her bf was an editor but in the BL spin-off, he got kidnapped by another guy she used to be involved with.
