Its similar because both have a similar storyline which is falling again and getting back with your ex , in both because of some misunderstanding they got separated but slowly those misunderstanding got cleared and later they got back with their ex boyfriend , well in both series one pursue and other runs away but at last fall again after the misunderstanding between them is cleared
They are very very similar . In Not Me the series there were twin brothers and both had totally opposite behaviours , if one is sun then the other is moon . In Twins the series it has the same concept one brother is friendly , playful but the other is cold with an unfriendly nature . In both the series the cold brothers ( Black in Not Me and Zee in Twins ) the other brothers tried to take their brother's places , when they took their brother's places people around them find iyt really strange as they have changed a lot suddenly. In Not Me because of White 's ( the friendly brother) many things changed, he became so friendly with the others and because of his sudden kind nature Sean fell in love with him ( White ) . In Twins also because of Spite's ( the friendly brother ) persuing and friendly behaviour First fell in love with him .... I find this two series very similar but according to me Not Me is more fun as it contains triller , suspense , romance , action soo I love this series so much as it matches my vibes....
In both the dramas the lead's soul gets into someone else body , in my stand in the soul wasn't able to come back inside it's real body but in vise versa at the end the soul got back into it's actual body in the old universe from where it came from...
