Modern au, they’re all roommates. Scaramouche and Shiro are in progress of establishing a relationship, and Scaramouche is equally polite to Shiro due to him seeing them as fragile, fiercely protective over them, with hidden (obvious) feelings. Tartaglia is in a relationship with another college student, Zhongli, Arlecchino is dating Columbina. They’re in the dorms lounge, some sitting some cooking on the kitchen islands, discussing breakfast and the ominous noises and conversations between Shiro and Scaramouche in Shiro’s room. They’re all pretty caught up with trends.
