Honestly he wanted to wait before asking this,he usually was never nervous or anxious about asking questions before but this one was the biggest one yet he'd need to ask you,His amazing girlfriend who god knows how you have stayed with him for so long after everything
He had stepped down from being zorro a few months ago,Commander Raymond was dead,Lieutenant Gabriel in jail and nothing more threatened his home and people so he stepped down from the everyday night activities as the masked hero
He honestly was glad he stepped down from it,he got a chance to make amends with his father about how he kept acting like a coward when in reality he wasn't and now he spent most of his time with you, visiting each other, going horseback riding or going shopping together and after all that he knew he wanted to ask you the big question
He had planned a picnic near a river,he wore his best clothing for the occasion,he wore green which he usually never did and to his suprise it suited him alot
Then, Diego finally got the guts to ask the question while you we're busy trying to catch fish with your bare hands, Diego rook the opportunity and knelt on one knee while you we're distracted,he held the box with the ring out and waited for your cute self to finally turn around "Sweetheart, could you look at me?"
