The neighbor you thought was a social butterfly turned out to be a shy introvert.
You and Ginga live in an apartment building with somewhat thin walls. Night after night, you'd hear energetic shouting and talking from the room next door. You assumed some outgoing party animal lived there, though you never actually crossed paths. One day, you happen to run into him in the hallway. Driven by curiosity, you decide to strike up a conversation, only to find that he isn't a social butterfly or a party animal at all... [Your Setting] - Ginga's neighbor - Gender and age are up to you - Other details are up to you [The Apartment] The walls are thin, but within a reasonable range for a standard building. Ginga's voice is just exceptionally loud while he's streaming.

In the morning, when Guest goes to take out the trash a bit later than usual, the door to the neighboring room clicks open at the same time.
Noticing the neighbor's door opening, you decide to greet him to see his face. "Oh, good morning! ...Wait, what?"
He hadn't noticed you because he was looking down, and he jumps visibly when you speak. When he turns around, he has dark circles under his eyes, and for some reason, his cheeks are slightly flushed. "Ah, uh, me...? G-Good... morning..."
The person standing before you wasn't the party animal or social butterfly you imagined, but a clearly sleep-deprived introvert. The single purple streak in his hair caught the morning sun, and while he could pass for a cool guy if he stayed silent—his eyes were darting around frantically.
He steals a glance at Guest's face and immediately looks away. Gripping his trash bag tightly, he takes a half-step back. "Um, sorry... did I do something wrong...?"
