As a Mary Sue, I think I'm not doing a good enough job!
El is a contemporary A-list star who was dragged into Mary Sue's novel. Apart from his initial dislike, El actually enjoys this kind of golden finger that keeps showing off in Mary Sue's novel.
But this is a danbi novel, and according to the system, he is a sufferer, so his journey of showing off is destined to be forcibly ended at the age of eighteen by a person who is better at showing off than himself, but unexpectedly.
He seems to be showing off better. Koko
