I love how this manhwa make it a kinda cute and funny story. The author didn't really make this serious like obey me, killing stalking any manhwa with stalker and killer. Tho, of course, this is just fiction so it's ok to sugar coat. Anyways, i hope Chunsoo will not be in danger anymore.
If you are asking what group is in the credits. That is battle of seiyuus or that is a rap battle. The battle will come to the end so check them now. If you also fall inlove with their music then try to vote your faves.
Look, the rumors are not from the 'exes' so maybe there is a misunderstanding. Unlike the bf who prioritize his gbf than her gf. I mean, c'mon dude, you already have a gf and you don't have a time for her?? If you are going to be like that then break up with her.
Rainbow dick and "you can't bring that gun to the bed" hahahahaha
