Both dramas takes place on high school and concentrates on one class. In both dramas the main lead is severely bullied. While the show goes on and time goes on they starts to find themselves.

They're different dramas but they have a similar feel to them.

Both are school dramas where there is bullying, family, friendship problems.
They both have romance.

Both dramas are involving police undercover. How the undercover cops fight the the dark world to survive and gain trust while not forgetting their morals and beliefs of justice. Both stories are filled with action scenes and carefully plotted and executed plans. Truly exciting to watch! The main characters are somewhat similar in terms of personality, filled with dark past, sadness, and rage but cannot show any of that to anyone.

The chemistry between the lead actors. Its where the characters innately trust each other. Both are feel good. Smile you takes a longer time getting there but is funnier(But not better).

War/Action, jealousy, love, suspense and excellent acting beautiful script all are qualities of "too late to say i love you" and i believe "bridal mask" doesn't come short except for that fact that "too late to say i love you" has way more romance. main characters are very similar.

well guy is possessive. uses a sister for revenge, threatens girl with fact he raped her into listening to him guy is super obsessed with girl an also there's beaches in both

because the guy miss understands her all the way to the end. both guys are really possessive, deny their feelings for the girl. girls are innocent well bee is a little more naïve then tawan

Both drama is about baseball. In my opinion H2 is more interesting.

Both of them have Joe Chen. She's the strong female lead again who can stand up for herself. It's another period drama. Funny aspect. Both dramas had kisses in 1st episode. Both is love hate relationship.

Both dramas have a girl who encounters a tragic accident on the train, therefore, causing the fake identity. There's the 2 guys n 1 girl thingy. Love hate relationship!! Epic period dramas!!

Its almost the same only thing its the girlfriend that takes the blame for everything it will make you a little sad and give you joy

Both hold that mysterious, vendetta type of storyline while both also try to stop from loving a girl that is somehow or another connected to the person who they're trying to get revenge on. Both are very wonderful and have great actors!

A group of people being killed off because they lost the game. An adult version shall we say?

I'd say this is kinda like the adult version of Kamisama. Same atmosphere and everything.

Personally, I think it has the same vibe: Teenagers, survival, blood shed.
