Both the drama gives the same feel. Not much of negative characters. Lots of cute moments between the main characters.
In both the dramas leads meet in university.
However the story line is completely different. If you liked one, don't miss out on the other.

It involves time-traveling and doctors that affect the past. Faith is about a plastic surgeon and Time Slip Dr. Jin is about a brain surgeon.

Both dramas deal with terminal illness, finding love and got the same vibe.

Both adorable which feature the two high school aged love interests living together. Serious second male lead syndrome in both.

In TTBY Tae Joon is a popular athlete and Jae Hee is the new girl. In GMC Uehara is one of the "top three" (most popular and handsome) in his school and Nao is a quiet less popular girl with a heart of gold.

Both action packed and full of plot twists. Whereas DOTS takes place in a different country, W is set in an alternate reality.

Both female leads are doctors and due to their relationship with the male leads end up in dangerous situations. Both dramas have the same amount of romance, the couples are adorable but obviously have a deep connection which shows through the casts' acting.

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.

Both dramas are full of suspense and in both dramas you'll find out the whole, real truth at the end and it probably will be unexpected

Korean actress speaking/acting as a vietnamese. It's not much I know but I had to think of Romance Town while watching Hanoi Bride.

Both are the stories about how a woman (a princess in QSD and an aristocrat daughter in TEOC) becomes - after facing many obstacles - the ruler of a country. Both are based on real characters, however their stories are dramatised for the shows.

The main difference is that while in QSD the heroine climbs the ranks first as a cross-dressed boy and then as a princess, in TEOC, the main character has to climb through the emperor's harem (and so the story, especially the first part, is more heavily focused on harem intrigues and conflicts), which is then replaced with more political plots.

Both have tragedy as well as a fair dose of angst (more so for TEOC though), well developed characters, are exciting and completely suck you in.

After finishing both there's this feeling of melancholic bitterness.

Somehow these two shows remind me of each other. Even though the original settings are definitely different, they are both featuring a "cold " (stand offish more so) smart man who falls for a unsuspecting girl.
The main guys are very similar. The main girls are a bit different. Boss & Me is a bit more mature than Love O2O (as far as romantic dynamics),

Both are really great light-hearted (and very cute) romances.
Especially,if you are looking for a get away from the plot twists and scheme in the other romance shows.

Both of these Japanese dramas are bizarre, twisting, sci-fi shows that center around mysterious hidden memories and a psychotic doctor. You won't be able to foresee the plot's development and conclusion, and once you're there you probably won't understand what happened either.

Both share many themes. My favourite being that constant question of: To leave or to stay. When the going get's tough, where do you draw the line among those you love and care about the most? In the end the answer is there is no line if you love them because love covers over it all. King's family offers an alternate ending for those Happy Home fans who were dissatisfied although while i enjoyed King's family just as much i'd venture to say the ending is not realistic but many people enjoy that sort of thing.
