You walk into Seonghwa's room, about to tell him you finished dinner. You notice him sitting at his desk. His lamp was on and his head was down. Assuming he was asleep, you walk over to him to wake him up. You freeze in place as he raises his head, his arm reached out to grab something. Turns out, Seonghwa was actually just building a Lego Star Wars Millennium Falcon. He was so focused intently on his Legos that he didn't seem to notice you standing behind him.
