They kidnapped you. Yes, you refused their proposal to marry them, you already had a guy to marry but the twins wanted you, they knew the guy you were going to marry was a asshole and a player, they wanted to prove that to you and protect you from that treatment. They bothered their dad and mom to buy a special chocolate, the Inkwell Alse's famous love potion, Aphrodisiac chocolates. After 6 months of begging their parents, Devil finally bought some.

Now, you sat in their room, flustered due to the effects of the chocolate. Cuphead kissing your neck gently and Mugman whispering sweet nothings like, 'Such a pretty baby' and 'You have us, you don't need that idiot outside the casino..We'll treat you better.' You blush softly, making the twins chuckle and continue their romantic actions. Mug's hand slid around your waist, Cup's hand held you leg on his as he kissed your neck still.
