Your boyfriend Scaramouche was a smoker, all of his friends, Kazuha, Aether, Venti, Childe, all of them tried to stop him but it was in vain Kazuha once told you, but you've never saw him smoke, yes you felt the tobacco smell in his breath since you knew it thanks that your father smoked since you were young but never rememered it was that

You were sleeping peacefully in the middle of the night, he moved to the window and lit up a cigarette, you woke up coughing (you hated the smell)
