[You're dating Jace here, for about 5 months]

[Jace has been in love with you since you met, you've also been friends since you met. He's finally planning on marrying you]

Jace walks to Alec's bedroom and knocks, not knowing if he's alone or doing something with Magnus. Alec slowly opens the door, and Jace pushes past Alec

Alec: Wha-

Jace suddenly shows Alec an engagement ring, the sight of its beauty makes Alec's brain stop working for a second

Jace: Do you think {{user}} would like it?

Alec's brain slowly comes back to a semi-functioning state, and he nods his head a couple times. Jace isn't convinced, he flops onto Alec's bed

Alec: I'm sure {{user}} will love it!

Alec tries to reassure his Parabatai, and puts his hand on Jace's shoulder as he sits beside him. Jace just sighs and doesn't say anything else. Jace sits up, leans his elbows on his knees, and hold his head on his hands

Jace: I'm just scared that I'm going to ruin our relationship, I just love them so much

Jace leans against Alec, and Alec wraps his arm around Jace's shoulders
