Alec was getting ready for his day when he saw an outfit sitting on his dresser with a note

Alec, put this on and meet me at the park

Love your boyfriend

Alec moaned and put the outfit that consisted of a, white shirt, black jeans , and dress shoes. Magnus was with Isabelle and Jace making sure this proposal was going to be perfect

"Is everything set" Magnus asked

"Yes dont worry warlock" Jace said

Magnus saw the little stage that Jace and Simon built. Isabelle and Clary were warming up Alec came to the park and saw candles and lights. Simon and Jace sat him down and went to help. Alec crossed his arms and smiled. Magnus got on stage and smiled as the music started.

The day started ordinary

Boys walking by (ooooh)

It was the same, old story

Too fresh or too shy (ooooh)

I'm not the kind

Too fall for a guy

Who flashes a smile

(It goes on for miles)

Don't usually swoon

But I'm over the moon

('cause he was just too cool for school)

And now I'm fallin' for ya

Fallin' for ya

I know I shouldn't but I

I just can't stop myself from

Fallin' for ya

Fallin' for ya

Can't hold on any longer

And now I'm fallin' for you

Now we're going steady

He's the cat's meow (meow. meow)

He says I'm his baby

And we paint the town (ooooh)

Alec smiled and clapped. Magnus hopped off the stage and went over to Alec. Alec smiled and kissed him

"Alec i know we had our rough patches but we managed to get through it. You are the bubble to my gum you're the gas that makes my motor run. You're the soda to my pop. What i'm trying to say is Alec you are the one for me. So with that Alexander Lightwood, will you marry me" Magnus asked showing a ring

Alec covered his mouth and nodded and smiled. Magnus got up and slipped the ring on his finger. Isabelle got a picture and cried

"What" Alec asked smiling

"My older brother is getting married" she said hugging him

"Ill still be the older brother you love" Alec said hugging Jace

"You know bro, no matter what were still gonna be paraibai" Jace said

"Yes we are" Alec said smling

The three siblings knew that nothing could tear them apart.
