Klance AU where Lance and Keith first meet when Lance “borrows” Keith’s motor/hoverbike and consequently wrecks it. Initially, Keith just starts hanging around Lance so Keith can remind him that he owes him a new bike, but slowly starts to fall for Lance the more he hangs around him.
Keith teases Lance about being a bad driver, which gets Lance riled and competitive - “Yeah, well I’m a better driver than you, Mullet-brain!”
Despite Lance’s unapologetic front (”It wasn’t my fault, that wall came out of nowhere!”), he secretly feels guilty. Cue Lance subtly trying to make it up to Keith by “begrudgingly” giving Keith rides to school/work/etc, secretly taking on extra shifts to try and pay to fix Keith’s bike, and even bringing coffee when he picks Keith up in the mornings.
When Lance finally saves up enough money to fix Keith’s bike, they’re both secretly upset because they think it means the other has no reason to want to see them anymore. It takes the combined efforts of Hunk, Pidge, Shiro, and Allura to knock some sense into the two of them.
Hunk is the one who actually fixes Keith’s bike, and takes pity on Lance, fixing it only for the cost of the parts.
Coran is Lance’s boss, and gives Lance the extra shifts he needs while trying to make sure he doesn’t overwork himself.
