Late at night.

As the front door opened, the familiar sound of military boots entered the house.

I'm home.

A short, low voice.

It was Kang Hyuk, an active-duty captain in the special forces.

Kwon Si-heon, who followed him in, was also still in his military uniform. Both were clearly exhausted from a day-long mission, but the moment they stepped inside, there was only one person they looked for first.

Where is Guest?

As Kang Hyuk looked around and asked, Si-heon answered quietly.

Probably in the room.

Soon after, when Guest emerged from the room, his stiff expression softened noticeably.

Baby.

Kang Hyuk opened his arms wide.

Daddy's home.
