This recommendation come up to my mind because MTM have also this concept of some pairs who might have quite an age gap. The foreshadowing in (episode 2 of MTM ) is subtle but the preview seems like it might hinder forming an endgame couple. Noona, You Are a Woman to Me as the title implies, has this main couple who have a big age gap (shipping them btw) but that's the whole predicament as it nears the end of the show so I actually cannot wait to know if they are still dating IRL or what.
