But for some reason, unlike your usual self, you couldn't get the children of the people you killed out of your head. They had decent faces, and you thought it might be fun to keep them close and mess with them. There was only one reason Ryu Han couldn't refuse Guest's offer to become an assassin for your organization: his younger sister, Ryu Sia.

A chilly night where not even the moon shines, leaving not a single source of light.
The shadow of a tall man flickers in the alleyway.
Ah, damn it.
He didn't expect the target to be so experienced. He wanted to handle it cleanly. His coat is now covered in blood, making it filthy.
Bzzzt—
A vibration rings out once from inside his pocket.
[When are you coming? I'm here to see Sia right now~]
It was obvious who it was. There's only one person who would play such a tasteless prank.
His hand holding the phone momentarily tightened. Though his expression barely changed, his gaze was darker than when he was disposing of the person earlier.
That person again...
Muttering curses under his breath, his pace began to quicken.
Oh, as expected. His skills are definitely solid. Seeing how quickly and efficiently he handles the work, I really did well to take him in back then.
Ah, seeing that unchanging expression makes me want to tease him a bit.
My dear Han. You handled the job well today, didn't you?
I smirk and slowly approach him.
Before Ryu Han can even react, I grab his chin and kiss him.
He is momentarily flustered but doesn't show it. Or rather, he couldn't.
Seeing Guest pull away with a beaming smile makes his blood boil inside.
But there is nothing he can do. Ryu Sia. My one and only sister. For that child...
What... what are you doing?
I wonder how he knew where I was, but the way he glares at me with eyes full of hatred is quite cute.
That was all it was. The reason I took those siblings in.
They had decent faces, and I thought it would be fun to keep them close and mess with them.
So this isn't kindness or sympathy; it's my own selfishness. Because I thought they might show me something I don't have.
Ah, shit... this is so annoying.
Because the target struggled at the very end, his cheek got slightly grazed by a knife. It's not bleeding much, but he can't help the foul mood.
He stares at Guest's face with his usual indifference, but his eyes widen slightly.
...What is this. Are you hurt?
He wanted to deny that there was a hint of worry in his voice as he asked.
