Well this idea isn't really developed either but I was thinking maybe the story could be told from sehuns pov cuz like why not and it would make more sense. So the story starts out with his brothers death and then there's his brothers husband who is crying and ststuff and maybe a year passes or so and they meet again and Luhans like oh hey sehun how have you been doing nd sehuns like I'm fine and Luhans like good. And then there's this silence and then sehuns like so how have you been doing and Luhans still kinda sensitive about it so he says he's fine but it's kinda quiet. But sehun doesn't pry or anything. And after that they end up spending some more time together kike luhan invites him over for dinner because he don't have anything else to do of anyone else to ask. 

And slowly they get closer and sehun is kinda beating himself up about it because this is his brothers ex husband and like hly crap he shouldn't be feeling anything for him he should be respecting his brother but luhan is so perfect and kind and sehun can't really help the way he feels about him. 

But somehow they end up kissing and it's like holy crap what just happened and luhan seems okay with it he's like quiet but then they end up standing on the side of the bridge or sitting on the side of a river and he's like I think it MIT be alright for me to let go a little your brother came to me in a cream and I know dreams shouldn't matter, yanow but it made sense to me. He said I should move on because it was okay with him and I deserve to be happy for the rest of my life even when he's not here and sehun is quiet for a little but then he's like does that mean you wanna try and luhA smiles and and he's like I think It does. 

So they do and there are moments where they're just silent, lamenting over something they've both lost but even though his brother is always hanging there, that's what's important and sehun can't change that. He slowly replaces his brother in Luhans heart and luhan heals and even though he's been through so much and the scars on his heart are so deep, he says that sehun was the one who sewed them up and made him feel right again and he will never forget that. 

A couple years pass a d sehun ends up proposing like Ian does in my big fat Greek wedding because I think it's just precious and luhan says yes and he ends up putting his old ring into a jewelry box in the back of the closet and he starts his new life with sehuns, filled with moments of serenity when they both wake up too early in the morning and love when there's nothing that matters but them. 

Holy crap that's emotional 

get ready for the other idea
