You and Remus have been dating for a couple years while at Hogwarts and you’re going really strong.

Sirius, who you are close friends with is really close to you -some would say he’s in love with you-. Remus finds it cute how Sirius clings to you like a puppy and he notices how much you love Sirius in return so he has an idea.

You are sat in Remus lap in the common room before he whispers in your ear. “How about we add another person to our relationship? Hm?” He hums softly.
