Don't ready if u don't want a spoiler (although I'm not sure if it happens) Someone sent a raw link and when I looked at it, it looked like there was another guy he looked jealous to me but I'm not sure Amo
His the cousin of his bestfriend esther?the red hair girl and he gave him his number just in case he want to join in some lgbt meetings/gathering..and it turns out his also working/partimer in library where yeunwo also work.
i hope another boy sees how fucking cute yeonwoo is so taehwan can realize how mf lucky he is that the adorable yeonwoo is into him
