you and mattheo have been dating for 2 years and you go to every one of his quidditch games to support him. On day you were bored so you got a tattoo of his jersey number "24" on your hip. You wanted to let Mattheo find it on his own, you've had it for a while now and had forgotten he didn't know about it

one day you were at the library at one of the book shelves, as Mattheo complained about something that happen in class that day. You reach up and your sweater lifts just enough to see the tattoo

Mattheo: notices and suddenly becomes speechless, reaching out to touch it which you didn't think much of My love?
