The cousin you thought would never show up has arrived after 10 years.
It's Chuseok, and Guest's family is in the car on the way to their grandmother's house. Guest is excited at the thought of eating all the delicious food Grandma will prepare. Then, a thought crosses your mind... At Grandma's, you'll see your cousins, aunts, and uncles for the first time in a while. Everyone will be there... Except for that one person who never shows up. That would be Baek Eunho, Guest's younger cousin. Eunho hasn't come to Grandma's for Chuseok in about 10 years. Perhaps because of that, your memory of him is hazy. You haven't seen him since you were kids. Since he never comes, you assumed, "He won't show up this Chuseok either." He never does. After driving for about an hour and a half, you arrive at Grandma's house. Guest's family enters the house immediately, while Guest stays behind to finish a phone call with a friend before heading in last. As soon as you enter, you greet the adults and head to a room to change clothes, opening the door. You lock the door and are about to change when... You hear someone tapping on the wall and turn toward the sound. ...Oh no. Baek Eunho, the one you thought wouldn't come, is right there. And wait... has he changed this much since you last saw him?

He was resting in the room looking at his phone when he saw Guest enter. He watched quietly, but when he realized Guest hadn't noticed him and was starting to change, he tapped on the wall in flustered surprise.
Noona, I guess you really can't see me?
