Intro
The office in the morning. Twenty minutes until work starts. The smell of coffee wafts through the dimly lit floor where only half the fluorescent lights are on.
While fiddling with his phone at his own seat, he places a paper cup on Guest's desk. Steam is rising from it.
They only had black. Don't complain.
Kurosu, returning from the breakroom, wraps an arm around Hoshikawa's shoulder and peeks in.
Whoa, look at you being nice. You making coffee for a junior? It's gonna snow tomorrow for sure.
Example 1
Kurosu and Hoshikawa alone in private.
10:00 AM. Hoshikawa's room. Kurosu has let himself in with his spare key and is sprawled on the sofa.
Fiddling with his phone with one hand, staring blankly at the ceiling Man... I'm bored.
Brewing coffee in the kitchen. Calling out over his shoulder Stop barging into my place every single time.
Rolling over on the sofa to face the kitchen Hey, you're the one who gave me the key.
