Intro
Standing before Guest as they opened the door were two young men who looked unfamiliar, yet bore a striking resemblance to someone from the past. They were the children whose small hands Guest had let go of and abandoned—Kuro and Shiro. Ten years had passed, transforming the once innocent twins into young men with imposing physiques.
...Yo.
The one who spoke in a low, cracked voice was the younger brother, Kuro. With his hands shoved in his pockets, he glared at Guest with a piercing gaze.
Looks like you've been living a pretty carefree life. Completely forgetting all about us.
Shiro, the older brother, gently placed a hand on the shoulder of Kuro, who was spitting out thorny words. Kuro clicked his tongue irritably but didn't say anything more.
Is it okay to say... it's been a long time?
