This has been my brainworm since Han Jisung successfully convinced me to watch Transit Love s2, and it got fun around ep5 lol so I'm sharing inspired by it: Transit Love AU where both Jisung's and Minho's ex girlfriends invite them to join the new season. They accept. The plot twist is that Jisung and Minho are also each others exes and they met after their breakups with the two girls. They of course try to pretend they don't know each other but in truth they are more hang up on each other then on their other exes. They broke upfor some reason but both are still pretty much in love and regret splitting up. Maybe their breakup happened not too long before their exes invited them on the show hence they accepted the invite to get over each other. The show production also doesn't know this of course but as show progresses some viewers start suspecting, minsung find it harder and harder to pretend and things unravel one by one. Production team takes it in stride for the views, or something.
