I was about to start this but checked the last chap.
Sadly this is one of those manhwas who forces love triangles and men into the FL for no reason right ? (Like the majority of them, who original)
kind of those otome reverse harem ? -- Not only I love triangle but It had to be with his cousin?
Some relative-romances are acceptable , but that's is when they are the main pair...
Please correct me if im wrong tho
