The Japanese drama also originates from the same manga "Zettai Kareshi". Both dramas are expected to share the same theme that is a love story between a human girl and a robot.

Both are about demon slaying swordsman in Warring States period. Both are based on famous manga.....................

Similar in terms of the 'time travel' aspect and the two main leads trying to change the outcome of certain things. They both go back to the '80s.

A big difference between the two is that in 'Life On Mars' the main lead goes back with his entire body, that is to say, he's there while his younger self is there as well. There are thus certain things he can't fix, since there is a paradox in play here.

In 'Boku dake ga Inai Machi' the main lead goes back in time in a completely different way. He goes back to the time he was a child and is IN his own 11-year old body. He can create different timelines, so the before mentioned paradox does not come into play in this drama.

Both are about Imperial Court of a Japanese shogun queen... ............................................................

Two women love the same man, car accident, loss of memory, serious brain damage, family forbids the relationship, despair, secrets.

Both are centered around mermaids, the male leads have sketchy occupations, and there are interspecies romances.

[Spoiler Alert] I got the same feels at the ending with this one as I did with Uncontrollably Fond.

The stories are similar due to its main characters and the historical aspect.

The female character are of low birth but end up falling in love and marrying the king or emperor and even though she encounter a lot of evil women who are also vying for the king or emperors favor she doesn’t let anything bring her down and remains true to herself.

The male characters are a king(Dong Yi) and an emperor( Queen of Han) who fall in love with women they shouldn’t love but do everything they can to keep them by their sides and protect them from other women in the harem.

Both stories are very good and have a few similar aspects but amongst the two Dong Yi is my favorite.

Cold quiet boy who becomes a Doctor. Not too bright girl who worships him. A long relationship ending in marriage.
