Similar Relationship dynamics without unnecessary misunderstandings and breakups. Both the dramas are sweet and has good kisses.

Ready, Set, Love is a faster, funnier take on a similar concept of a group of pretty boys who are trapped and get made aware of their situation by ladies from the 'outside' world. If you liked the second leads and/or the rescue plot of Love Crossed, then RSL is definitely worth checking out.

Both are historical, have a dark vibe and open with the concept of a "ghost marriage" that then involves murder mysteries.

Under Your Bed takes a more-creepy-less-sweet approach to the very similar situation in 3 Iron, but is very good nonetheless.
While 3 Iron is near dialogueless Under Your Bed is a lot of narration with occasional interactions. I love both films despite shipping the leads in 3 Iron while standoffishly.. understanding(?) the leads in Under Your Bed. Under Your Bed is certainly a movie to watch and appreciate from a good film perspective, not one to go into expecting to be rooting for your lead character. As long as you can realize that a film can be about something bad without promoting said bad thing, I think you’ll enjoy it.

Both movies show a broken woman lost in the world. I got a similar blue vibe watching them. Mirrored Mind has a more depressive-calming feeling. Ritual has a depressive-sometimes-caotic feeling.

Both are light historical dramas in which the FL disguises herself as a boy to enter a male-only school and ends up roommates with the ML who she clashes with at first.
