Disclaimer : It's my own pov so please don't judge as everyone has their own taste.

My man is cupid , this drama I agree there's some overlapping plot like past life connection but the whole drama was a 9 / 10 because I have seen many dramas like King the land , A good day to be a dog , My demon I dropped these dramas mostly at ep 8 or 9 because i found the storyline to be repeated somehow or there wasn't any spark to keep going . Past life connection is a trend these days in k drama but we shouldn't judge the drama because it has this plot , a good day to be a dog and mg demon has past life connection too but the story line isn't worthy enough. My man is cupid has NO BORING EPISODES !!!! It's such a crucial point to have no boring episodes because people do drop dramas due to this thing. The way how each episode kept me awake , made me use my brain cells to solve the mystery . It's a very good drama to watch if you need romance but a bit less and a good storyline to keep u invested throughout the drama. Because sometimes in a drama only romance drops Its points. Ahh for the rewatch I think i would rewatch it again after 1 year or so..
