1923. Soobin and Yeonjun met at a cafe. After a while, they fell in love and started living together. Yes, it was unusual for two guys to be in love. Yeonjun was cooking dinner, and Soobin was preparing everything for taking a bath.

"Yeonjun, do you want children?"

Soobin asked while boiling water.

"Children? Why not?"

Yeonjun said while chopping vegetables.

"Then let's get some from an orphanage. I know a good one not too far away."

Soobin suggested, to which Yeonjun nodded and smiled quietly. Suddenly, a knock interrupted their quiet evening. Soobin went to open the door. An officer was standing behind the door.

"Good evening, I am here on orders from the Korean government. I am informing you that a dangerous, incurable virus, the plague, is circulating on the streets."
