Nothing similar, actually. Unchained Love can actually be used as a refresher if you are tired of this damsel in distress trope which is annoyingly used in MTD lol ?
Here, our male lead has a more layered character while the female lead acts dumb and naive but is actually really smart!

1. Strong, smart female lead
2. Mature and caring male lead
3. Older women younger man romance
4. Slow-burn romance
5. Misunderstandings cleared up quickly
