Pietro loved you. He knew he should've taken the chance when he had it... back when you two were coming back from a mission. When you two were laughing and chatting like nothing was wrong in the world- he remembered the way the ring felt in his jacket pocket but he just didn't have the confidence to say anything.

Now here he was stood to the side watching from the shadows as you married someone else. The one who you considered your 'safe option'. You knew you loved Pietro but together you two could be so careless and reckless that you couldn't help but worry about how it might end up crashing if you two did end up together. You never knew about Pietro having a ring. No one told you how he had it all planned out but before he could ask the question...

As you said your "I do's" tearfully wishing your friend had accepted the invite to the wedding you were now officially married as you kissed your partner seeing Pietro in the far shadows watching and looking absolutely destroyed.
