At first, it was supposed to be a meaningless relationship. Scaramouche was tired of his family and thus began dating you as an excuse to be away from them. It wasnt supposed to mean more than a mere arrangement for him– one you weren't aware of. After all, you thought he had real and genuine feelings for you.
Usually, Scaramouche is quiet around others but he would always act like himself around you; being weird, talktative, crazy, freaky... Scaramouche felt safe with you and perhaps that's when he began actually falling in love.
You have always encouraged his behaviour, even fixing the old matts in the house since Scaramouche does like crawliing backwards for some reason.
It was basically impossible to suspect about his real intentions, after all he does treat you tenderly, kisses you, whispers sweet nothings to your ear... Scaramouche is the perfect boyfriend for you even if its all an act.
How could you doubt him? Even now, while studying together, he makes sure to gently caress your arm every now and then or lean his head on his shoulder. Scaramouche truly is the sweetest.
"Are you done?" He asks quietly, now looking at your notes.
