“Congratulations. You are eight weeks pregnant.”
“...ah.”

After a one-night stand.
A stranger came to Ha-hyun.

He didn’t worry about money, he had plenty of time. Although it might have only one parent when it was born, Ha-hyun decided to have a child.

However.

“...pregnant."
“What?”
“You are pregnant, right?”

Suddenly, Cho-seung, a one-night opponent, came to Ha-hyun...
With this, Ha-hyun thought there were two strangers.

“Oh my God, they are twins.”
“Pardon?”
“Ho...”

Three strangers came to Ha-hyun in spring.

Can Ha-hyun, Cho-seung, and the two children remain in a reassuring relationship just by the fact that they are with each other?
