Anyway, here is a proposal theory based on the trailer (the MALEC dance scene)

If you want me to do one on the MALEC training scene, vote or comment on this one-shot (I'll probably do it either way)

Alec's POV

Today was it. The day I will finally propose to Magnus. I asked my family, well, sister, if I could take the day off and she PRACTICALLY SCREAMED AT ME and insisted I take three days off instead, so I just said yes (mostly because I didn't want her to scream at me anymore).

"Alexander, love?" Magnus muttered in his sleep and somehow snuggled even closer to me.

"Yes, baby?" I smiled, playing with his hair.

"I love you"

I sighed in comfort.

"Since you got the day off, I was wondering if I could teach you how to dance?" He spoke, opening his eyes.

"I would love that," I whispered.

Ten minutes later

"I can't do this, I give up!" I groaned, falling onto the couch in defeat.

"Now now Alexander, you're not giving up until I'm gone, do you understand me?" Magnus sighed.

"I keep stepping on your feet! By the angel, I also keep dropping you when we do the dip (I don't know the official name 💀)!"

"Alexander, you're fine. Just think of the reason why you're dancing, not your movements" Magnus held out his hand.

I sighed and grabbed Magnus's hand, pulling myself up. We started out slow, making my heart beat fast.

"Move your hand," Magnus whispered. I looked at him confused. Magnus sighed, moving it in the right position and twirled, making me catch him in my arms and dipped him down. We stayed in that position for a while.

"Magnus... marry me," I whispered. Magnus looked at me with wide eyes before jumping up and pulled me into a passionate kiss.

"Yes, yes, yes!" Magnus whispered between kisses.
