Both have beautiful male leads
Both have bromance and BL undertone?
And both are historical

So, WATCH IT if you want

Both are about murderers and their lawyers who fight against the death sentence.

The World Between Us is about the murderer´s family and the victims family and Hokyto is about how a child turn murderer.

Its hard to really go into the similarities of the two movies without spoiling things. From the outside they might look totally different but there are a few things they have in common, i suggest you just watch both

Both movies are Thai arthouse productions set in a forest, have plot that's confusing at times and are beautifully shot.

Both the couples meet when they seat in adjacent tables alone in a restaurant and they sit together to save table space. In both dramas the FL is still in love with her ex and the ML is younger.

- both about the world of psychiatrists and the importance of mental health
- both include romance and medical

Don't MISS out. Bro..friends??. Supernatural horror + investigation. Too much worry for one another u would have thought they 2+1 have been friends for a long time. Expression, emotion is what u will get from them like untamed, guardian. Got recognition from international awards. Waiting for the movie

The plot in both of these series are similar. A virtuous hero chosen to lead the Mohist sect during the Warring Era China with a quest of abating war between the neighboring nations while soliciting unification for peace.
All the while, high ranks in the king's court felt threatened by the rise of our hero movements as acts of rebelling. Thus, they accused these heroes as spies with a malicious intent to bring down their nation. So they sent orders to post rewards for their head.
Beside the plots are alike, both of these stories also have many similar characters.
The only difference in these two series is that The Legend of Quin is not about time travel.
If you enjoy A Step into the Past (2018), I recommend The Legend of Qin (2015).

It looks much similar to V.I.P. Sun woo and Jung Sun become like detective who looking for her husband's cheat with someone. They check through their husband's phone too. They're much same but one thing V.I.P is much interesting when it happens to be someone who has been affair with Jung Sun's husband. Her husband cheated on her with another woman in same workplace where Jung Sun working at VIP. So it would escalate the climax!

The characters in both dramas have love and compassion for their jobs, and a nice balance between being professional and having fun as colleagues and friends.

Okay so there aren't very many similarities however, the main couple of Touch Your Heart is played by the same actors who play the grim reaper and Sunny in Goblin so if you couldn't get enough of that couple, I would definitely recommend! Lee Dongwook and Yoo Inna have great chemistry and they are so cute in Touch Your Heart.

Similarly for both dramas the leads have opposing views on marriage.
One party desperately wants to get married and the other does not.

Both male lead act like bad boy, but in the end they´re soft.
In She´s dating the gangster the main plot is that main lead pretend to have relationship with main female lead, so his ex will be jealous, and return to him.
In our times both leads have their crushes, but they are together, so these to work together to separate them.
In both they fell in love together and have sort of happy end.

They both are same. Both are in set up of josean historical era. The main lead is a crown prince.
In both of these, crown prince's personal guard dies. They both includes a dangerous plaque which is across the country.
Due to the plaque, humans were turning into zombies who crave for flesh and blood. Both of them have same situation, i.e.,survival.
Everyone is fighting for their life. There is conspiracy between ministers to become king.

Although these two are really different as Anniversary Anyway focuses more on the pleasing side of the teenager's life and on the other hand Our Nineteen gives equal importance to all the sides of life of different teens-Happy, Painful, Beautiful, Memorable, Fun and treasurable moments of life.
Anniversary Anyway have episodes of less duration than Our Nineteen. But the thing that have in common is how sweet the development of relationships are in highschool.In short,Romance is the thing that makes them similar- just sweet and delightful :)
