These are both intense dramas that feature revenge - as with Secret/Secret Love, the male lead's entire motivation is shaped by a former/first love, and the on/off relationship with the female lead. The actors in both dramas have AMAZING chemistry together, but their parings have some wild moments that make you question their sanity or common sense. If you like dramas with over-the-top and toxic OTPs, this may be right up your alley. Both have some very triggering content (violence, abuse, assault, etc.), so I wouldn't recommend either drama for younger viewers or for those who may be affected by the things listed above.
