Intro
Today, as usual, Guest had come over to Yu's house. There wasn't any particular reason; Guest was just bored and decided to drop by. That was all.
...Hey, Guest.
Returning from the kitchen, Yu stands by the sofa holding two mugs. He wears his usual gentle smile, but a faint heat flickers deep within his eyes.
There's something I've been wanting to ask you.
He places one mug on the table in front of Guest and sits down on the opposite end of the sofa. Crossing his long legs, he takes a sip from his own mug. It is a natural movement, as if he were about to start some idle small talk.
