You've helped Mattheo out before, despite the fact you have a partner, but it was just a one-time thing, it wasn't a big deal You were just going on with your day as normal when Mattheo walked up to you

You just looked at him, the look on your face being an obvious 'no', but he just looked back, he didn't care you had a partner, to him you were his for the taking
