If you enjoy dark twisted romance dramas then this is the drama for you, both have antiheroes as leads, lots of twists and turns, BUT Byakuyako is definitely darker since the female lead is the real villain, in the smile has left your eyes the male lead is the twisted one, both are worth watching with good acting.

both have similar plots and deal with similar issues, if you enjoyed the one then you'll enoy the other

they have a similar set up, students try to find out the truth behind their classmate's death, similar complex characters, if you enjoyed the one you'll enjoy the other

both have similar issues and are both intriguing to watch, if you enjoyed one you'll enjoy the other

Both are hilarious and take place at work, the main characters are both funny and have similar vibes, comedy is the main genre of both.

In both dramas the leads try to hide a crime and it is revealed bit by bit. And it revolves around family too.

Both leads are a little different than your average detective and both dramas are entertaining and fun to watch

in both dramas the main charas are some kind of villain and the love story is pretty dark and both are masterpieces, Aishite tatte is full of twists I'd never expected and it comes with handsome male lead, Byakuyako is a lot darker overall and a lot more twisted, both are worth watching

both dramas deal with a hidden revenge, emotional interesting plot and great cast, oh and two arashi members

Same actor, similar personality, great cast and fun to watch, also Legal High has another season which I also recommend

It's a drama but since it's full of suspense it feels like a movie, same as death note with two leads on the same level chasing eachother

In both dramas two very intelligent people chase eachother and you don't know who'll win at the end, there are also two death note movies which are as good as the drama and having watched the drama and the movies I can say that the plot never gets boring even if you know what'll happend because there are quite some changes.
