Kim Min seems to be good at it; it doesn't look like a simple setup for the broadcast, so people seem to like it

‌Even just watching him drive nails, he's not a professional carpenter, but
he's good for an amateur.
Even just seeing how he applies the sealant, you can tell he's done it often.
The way he sets things up so he doesn't step on them by mistake
shows that this isn't just for the broadcast, but a scene from his daily life.
He might be doing all the maintenance he's been planning to do at once while filming,
but it's obvious that this isn't something he just set up solely for the broadcast without doing it normally.
