Troublesome Sister น้องสาวจอมก่อปัญหา

Troublesome Sister Eun Seol, who always took care of me and played with me when my friends wouldn’t play with me because I was sick. The problem is, even when you’re an adult, you still treat them like children. In the end, even when I went to university, the nickname “Baedung-ee” spread and I became an outsider. Now, even though you look like a man in your sister’s eyes, you have to treat her like a child.
