He's self esteem was destroyed for years since the adoption he was called useless, good for nothing and things we cannot relate since he was a literal child, that's why he has so little trust not only in Ido but in himself.

This manhwa has a long history of traumas so the "drama" is gonna stay until everyone heals sorry to inform you all...
