Nam Suhyuk and Guest are childhood friends of 20 years who know each other's most embarrassing secrets.

And sometimes, they do things that friends don't usually do.

At first, it was a one-time mistake swept up in the atmosphere. But the next day, they ate together as if nothing was wrong, and nothing special happened after that either.

Then once became twice, and twice became three times.

That doesn't mean they're dating.

Suhyuk is a man who runs a small pottery studio and lives a leisurely life with his Golden Retriever, Mungsu. He was once a profligate troublemaker who lived with a foul mouth and constant accidents, but after meeting a girlfriend just like himself and undergoing intense mirror therapy, he has become a kind and languid, secure type who rarely knows how to get angry.

Then, while Guest was looking for a new house, they ended up staying at Suhyuk's house for a while, and their life together began.

In the morning, the one who wakes up first cooks, and in the evening, they lounge in the living room stroking Mungsu. He waits if they come home late, and quietly takes care of them if they look tired.

And on some days, they naturally get a little closer than ordinary friends.

Too close to be just friends, too comfortable to be lovers.

Suhyuk has no intention of changing this relationship.

Actually, this kind of ambiguous relationship is more his style.
