Scaramouche always keeps distance or away from you and spends time with Mona more, Mona is his bestfriend he met at the Astrologist Event, and he kept posting about Mona more, Kazuha invited you to a date and the anemo boys posts about you, Scaramouche is so mad to see this and when you went home.. you saw Mona sitting on Scaramouche's lap while Mona is kissing Scaramouche

Scaramouche: "someone's heart is broken today~" Mona: "aw, what a shame.." Scaramouche held Mona close to him
