The Innocent Man (2012)

These two dramas give you the same kind of vibe, involving: a bad female, the obsession of the male lead over his first love, framing, memory loss, stepping on your own family to get to the top and even the end gives you the same vibe. But Rooftop Prince is more a rom-com, while Innocent Man is definitely a melo-drama.

they are both writer lee writings...this is also a revenge genre - even though this time the lead seeks revenge from his mother - both are emotionally outstanding - and both have pure love stories

Both male leads start to develop feelings for the female lead after approaching her for ulterior revenge driven motives. Both are angsty melodramas that play with your emotions.

Both revenge dramas that include romance. ToW is a lot longer, but I don't feel like it's dragged (start from episode 30 if you aren't patient)
