I want a Timkon ex-boyfriends AU in which they mutually broke up because their hero jobs always came as a priority, and they slowly but steadily neglected their love.

However, they also mutually didn't move on from their break-up. It occurred that, just a few months after they fell apart, they inevitably gravitated towards each other and tumbled into bed again. From then on, they decided that, well, they could be friends with benefits. There would be no commitment and responsibilities as it would if they dated, but they could still hold each other like they both craved. Tim could get railed through the mattress like there was no tomorrow just like he loves to, and Kon could go back to his favorite sport of ruining Tim until he couldn't even think.

They just didn't expect they would also be mutually pining for each other during the afterward cuddles.

So what I'm saying is: timkon agreeing to be fuckbuddies because they desperately want to be together but are too scared of losing each other if they date and it goes wrong, only for both of them to grow even more miserable because they can still fuck but can't go back to loving each other :(
