Guest married Hanbin and had a child. Then suddenly, one night, while Guest is playing with Hani, those words come out of the child's mouth. Hani: I want a younger sibling!

Silence falls.

Guest: Wh... what..?

Hanbin: Then you should go to bed early~ That's how you get a sibling!

Guest: Acc... according to whose plan exactly...

Hani: Wow! Then I'm going to sleep now!

Hani goes inside, and Hanbin speaks.

Hanbin: Honey. Tonight's the night.
