how about a modern!shance au where lance is driving his rusty old hand-me-down car one day and it breaks down, so he looks around for the closest mechanic shop to fix it up.
so lance goes there, fully expecting a grumpy old man to greet him but instead, enter shiro. lance is so caught off guard by how gorgeous this man is he barely remembers any details about his car, but luckily shiro is patient and eventually works out the cost and estimate to fix it. lance is so charmed, and soon he relaxes more and starts to make jokes, even a flirt or two to test the waters. hes not sure what chances he has here, but shiro doesnt seem bothered by it, even laughing along with everything, and lance wishes he didnt have work later and would much prefer to stay here and chat with this beautiful mechanic because whoa.
a few days later (and having thought about shiro a lot) lance goes back to collect his car, and shiro catches him up on all the new updates until soon lances realises oh, im not going to see him again. he loses his nerve to ask him out, because really, shiro is a friggin catch. so they part with a handshake and a sour feeling in lances gut.
but then, not week later, and lance gets the idea of bringing in another car so he gets to see shiro again. he borrows his brothers old honda and drives over. shiro looks surprised to see him, but not disappointed, and smiles and gladly says hell help to fix up this car for lance too. lance beams, goddamn butterflies in his stomach, and savers every damn second.
the days go by, and soon the weeks as well. lance asks his family or friends if they have anything they need fixing, finding any excuse and gladly brings it over to shiros shop (one time he brought his dads old radio, claimed it was priceless)(another time he dropped off an old clock he claims his grandma would cry if it ever broke)(one time, he came around with nothing, offering shiro a coffee and going on about his day). most days he lingers around and chats to shiro as he works, and lance learns a lot about him and feels himself fall more and more for the guy, thrilled that shiro enjoys his company just as much.
at this point everyone is wondering why lance hasnt just asked the man out yet? “because oh my god boy youve got it bad.” and lance will flush crimson but never deny it. “its scary, okay?” hell protest weakly.
and so one day, after walking back and forth in front of the shop and trying to finally muster up the nerve, he swallows his fear and steps inside, the familiar chime of the bell going off. he walks over to shiros office, opening the door without even thinking, and finding shiro in a mess at his desk, small parts littered everywhere and a youtube video on how to fix clocks currently playing.
lance pauses, eyeing the scene curiously until shiro finally looks up and notices him.
“oh - lance - I -”
and lance is so confused. “wait, i thought you said you knew how to fix clocks?”
and shiro becomes really bashful, rubbing at his neck and refusing to meet lances piercing gaze. “uh, i kind of… lied?”
“what?” lance is so lost.
shiro starts stammering. “I, uh, said i knew how so i could… keep seeing you. i.. didnt want you to leave and find someone else to fix it.”
and after what feels like ages lance… starts giggling. he cannot believe it, honest to god cannot believe how lame they both are to have not even realised that it was mutual. so hes full on laughing now, and shiro takes it the wrong way and grows hurt, so lance sobers up quickly and closes the remaining distance between them to smile so big and wide, his face heating up.
“I wanted to keep seeing you too. shiro, shiro i brought in three cars to see you, shiro, man, i had to look up what parts were even called just so i could figure out what the hell i needed you to fix.”
and shiro breathes out an awed “oh” and lance is so happy he feels like he could fly, holy shit. shiro stands up, and when he reaches out to gently brush their fingers together lance is pretty sure he has a heart attack right then and there. and then shiro says in a really soft voice:
“you’re so beautiful.”
that’s when lance is sure hes died and gone to heaven above. lance.exe has stopped working. hello, 911, id like to report a murder.
“god, shiro, have you even seen you?” he laughs nervously, shying away.
“im serious,” shiro pushes gently and picks up a hammer without breaking eye contact. “this is not …a drill.”
and lance feels his eyes grow wide, so completely gone he cant help but blurt “oh my god marry me.”
shiro grins, his thumb rubbing lightly across lances fingers. “let me take you on a date first. but perhaps we should take my ride, yeah? not sure i trust you behind a wheel just yet.”
and lance punches him playfully, but his heart wont stop beating loudly in his chest because he finally has a date with shiro.
