The Annoying Older Girl Next Door

Back when I was sick and my friends didn't want to play with me, Eun-Seol was the kind older girl who always took care of me and kept me company. The problem is, even now that I'm an adult, she still clings to me and treats me like a little kid. Because of her, even in college, I ended up with the nickname "Baby" and became a complete loner. Now, I have to make her see me as a man if I ever want to stop being treated like a child. (Source: DAYcomics) Note: Chapter count includes an epilogue.
