18+End Troublesome sister – raw >> Manhwa

Summary

Eun-seol, a grateful older sister who always took care of me and played with me when I was young, when my friends didn’t play with me because I was sick. The problem is that even when they become adults, they cling to them and treat them like babies. In the end, even after she went to college, the nickname ‘Bae-Dongi’ spread and became an asshole.
