(I wrote this way too fast because i needed to write this down before i writers block kicked back in so there are probably spelling mistakes, grammar issues (theres always grammar issues with my writing LMAO) goodluck!)
I'm imagining Reader, who is a traveler who goes overseas often. They go to Piltover and meet Vander and decide to join their cause, becoming a merchant to get extra money to bring in.
Reader is getting ready to set sail with their crew and Vander pulls them aside just before they leave and gives them a promise ring. Once they do set sail, Reader waves at Vander until hes out of sight.
While they were away, Vander, Silco, Connol and Felicia helped him plan an actual proposal. When Reader did finally return, they were expecting to be proposed to the second they got off of the ship but to their surprise, they were just welcomed back normally. After the next few weeks, Reader stays suspicious but in the end figures that he's going to wait until after they beat Piltover.
Once Reader is no longer suspicious, they set the plan in motion.
One day, Felicia invites Reader out and they walk around topside. Eventually, Reader is dragged into a shop and Felicia pretends to look around before "spotting" an outfit that Reader also likes. Felicia convinces them to buy it, and they do. They head back and Reader styles the outfit and while they were changing, Connol told her that everything was ready and they both sneak out.
While Reader and Felicia were out, Silco and Connol had been cooking. Reader faintly smells their favourite food as they walk out, all dressed up and see that the only thing waiting for them was a note saying that Felicia had to go.
Before Reader could change Silco shows up and asks them to help him gather some supplies or something. He insists that they don't need to change and they head out, grabbing bits and pieces from various shops before heading in a direction Reader doesn't recognise and before they can ask about it, Silco hands them a blind fold and asks them to put it on. Which they do, now incredibly suspicious (and slightly concerned).
Silco leads them along until they stop and he walks off, and Vander tells them to take off the blindfold, which they do. Immediately seeing that they're stabding ontop of an old building, a gorgeous view of Piltover and the sky, the sun setting, casting a beautiful glow over the city. Two chairs and a table, covered in their favourite food and drink and fairylights strung up all around. And Vander, dressed nicely and looking uncharacteristicly nervous.
They sit down, eat and talk and eventually the sun has set and they're sitting in comfortable silence when Vander breaks it and asks them to stand up. Weeks of practising what to say go straight out the window and he stutters his way through a small speach before he gives up and pops the question, kneeling and holding up a small box.
Reader stares down at him in shock, completely silent- everything he just said processing in their head and as Vander goes to stand up- akwardly apologising- he gets tackled down by Reader, who happily says yes.
...
NOW IMAGINE
Every year, at the same time, on the anniversary of his proposal. Reader puts on the same outfit, grabs their favourite alcohol sits in the same place they sat on that day. Mourning the life that could have been.
