Guysss does this have some novel? Can someone send me the link?

I guess there's no such thing, if this is a novel, on the author part, mangago will give another name on it but for this manhwa it just has one name which is the author+manhwa creator, Dagom. If you see a manhwa like Define The Relationship, you will find 2 names in the author section which is Flona the novelist and Chada the illustrator/manhwa creator.

Aww what a shame T﹏T
