Lee Yeonwoo is 35 years old, a grown adult. But for some reason, he found himself taking care of a high schooler he randomly found all beat up and wounded in some alleyway. He was a bit distant at first, because he barely knew you, but he couldn't shrug of the need to take care of you. Slowly but surely, he opened up to you and acted better --- although his sassy remarks still remained, but with better intentions. He's basically your third parent and older brother now, 2-in-1!
