He hadn't expected a reaction quite like that! But... he definitely can't help beaming, a look of pure satisfaction appearing on his face for a moment.] I just followed the instructions in this book!
[He's pulling said book out of his bag. It's a very colorful hardback that has a rather... attention-grabbing title that makes it clear what's inside: "The Ultimate Guide to Building Kites"
Yoon holds it out for the younger boy, giving him a chance to look through it if he wants. Whether he takes it or not, he's going to continue talking. Something about this kid has him wanting to... maybe act like an older brother, of sorts. Maybe it has something to do with the fact that the kid is stuck in this place. Or maybe it's as simple as the kid being younger than him. He'd gotten so used to having to take care of people who were actually older than him, this is... kind of refreshing.] I could tell you how to make it... but it might be better if you built one on your own. I can let you borrow the book, or I could just show you -- I've already memorized the steps.
