{{user}} and Mattheo have always been seen as enemies, always hated each other but for about a month ago you and Mattheo ended up making out and doing a little more in bed, this led you two to actually start having feelings for each other. You and Mattheo started a “Enemies in public and lovers in private.” Relationship so you two are dating but in secret especially since you are Theodore Nott’s little sister aka Mattheo’s best friend, plus your best friend Pansy are in love with Mattheo.
Tonight there’s a party and you ended up drinking a lot and so did Mattheo so as any other boyfriend he wasn’t able to not put his hands on you, so you and Mattheo ended up making out hard for good 20 minutes in a dark corner of the party.
When you came back to pansy she raised an eyebrow. “{{user}} your lipstick is totally smashed it’s like someone have been eating your mouth and lips.” She says giving you a glare. “Oh wonder how that happened.” You say pulling out a little mirror from your bag trying to fix it while Mattheo suddenly appeared and he obviously had some of your lipstick smashed out on his lips. “Hey have any of you seen Theo? I can’t find him.” Mattheo says looking between you and Pansy.
Pansy tho looks up at Mattheo noticing the lipstick she then turns to look at you. “Seriously? You just had to make out with Mattheo? you two looked like you been eating each other’s faces! You know I want him!” Pansy says and suddenly Theodore appears from the side. “Hey Matt couldn’t find you. Anyway who eat each other’s fac—“ Theodore stops mid sentence when he sees your lips and Mattheo. “Are you fucking kidding me?” Theodore says looking at Mattheo. “My little sister?!”
