Soobin and Yeonjun have known each other since childhood, went to the same school, graduated from the same university, and work in the same office. Soobin and Yeonjun often liked to spend time together at their dacha when their parents went there on weekends to relax. The house was owned by Soobin's parents, but they soon gave him the keys because they knew Soobin loved silence and a break from the world, and the dacha was a great place for that. Soobin then decided to invite Yeonjun to go there like in the good old days.

Soobin and Yeonjun walk into the dusty attic of the country house and notice a small hut made of blankets with a garland around it.

"Wow..this is still there, I'm surprised."

Soobin smiled.

"Remember how we shared secrets here when we were kids? There's even a hidden chest with our valuables and notes somewhere here, I think we can find it.."
