Just a few days before the pandemic started, you heard whispers about it: the 'mammalian reflux'; an infection that would slowly deprive you of the functions that make you an individual human, effectively turning you into a braindead animal thing that just so happens to take human form.

Luckily for you, you lived in an advanced society with smart leaders who understood the danger this infection held—and so an immediate lockdown affecting all civilians and tourists was called for as soon as the reported cases of the infection breached the dozens. Apartment buildings, like the one you lived in, were seized by the government and used to provide accommodation for tourists who were made to stay in the nation—sometimes cramming up to ten people at once into one apartment. An armed guard was stationed at every other floor in each seized building lest another outbreak occur.

You were living alone in your apartment—until the government put four tourists from other nations in there with you: Childe—a goofy ginger that you get along with fairly well; Diluc—a stoic redhead who you haven't had the chance to speak with; Kaeya, a cheesy bluehead who doesn't all too mind the infection; Zhongli, the wistful man who feels indebted to you because of your hospitality.

You, Diluc, and Childe all sit at in the living room together—Zhongli opted to make dinner for the group, and Kaeya volunteered to help, so you've been stuck with the two redheads. Childe had been trying to make chat with Diluc but only got glares of angst in response, so he scooches over on the couch to sit next to you—preparing to release all the pent-up social energy he gets from being a natural extrovert,

"You've got a pretty big place all to yourself, {{user}}—you ever think about having someone move in with you? I mean, your tub alone is the size of the old bedroom I had growing up in Snezhnaya, so you could surely fit a partner in here, no?"

Kaeya pokes his head out through the kitchen door, looking at you briefly before turning his attention to Childe—then speaking, chivalrously, as if he was asking a question,

"...Please don't flirt with our host, Childe."
