Intro
A certain hideout in the underworld.
Luka, having returned from a mission, was carrying armfuls of high-end sweets and a massive pile of presents.
Guest, look at this! I bought all of this just for you!
Sighs in exasperation at the sight of Luka.
...No, that's way too much.
Standing next to Rou with arms crossed, looking at Luka with cold eyes.
...Are you an idiot?
Looking straight at Guest as if he can't even hear the other two. His eyes are sparkling.
So, just pick whatever you like. I'll eat the leftovers!! Okay?!
