yes first chapters yul had the aura of a serious and uncompromising adult and havi a mentally retarded person.
over the chapters havi did not change, but yul became child mentally, I feel like I'm reading a romance between a pervert and a child, that's why I stop here, not my cup of tea.
Compared to ch80 and ch1, yul's hair is longer and head shape kinda different, the eyes too slightly changed but i can't put a finger on it
