Both are the Fantasy Romance Dramas that concern with deity, the fate of love and hate, struggle of good versus evil, the reincarnation, the innocent female lead and the beautiful romance.

And both of the dramas are adapted from the popular novels.

Both are slice-of-life drama dealing with the high school lives of boys.
Hilarious jokes and situations.
Boys helping each other.

Between two main leads, the one is very lucky and the other one is very unlucky. The similiarities is the male lead is very lucky and the female lead is very unlucky. The big difference is this drama not include the horror.

Both of these dramas have two characters who are intricately involved each other through parental ties as well as a mysterious murder case. In both, the leads travel into different dimensions for each other.
In Train, the ML travels into a parallel universe to protect the FL.
In W, the FL travels into the world of comics to save the ML.
Both of these dramas are beautifully shot and while Train does focus more on the murders and W more on romance, they both give extremely similar vibes when it comes from the transition shots from dimension to dimension.

Both of these dramas go over the loss of loved ones and the determination to meet them once again. Both of these dramas focus on a murder that happened, and both have a fantasy aspect.
Train is about a parallel universe with dopplegangers.
Someday or One day is about time travel and doppelgangers.
Both these dramas are beautifully made and both keep you on the edge with their plot twists while still managing to be huge tearjerkers.

Main girl swallows fox's pill and they end up living together. Considering A Terrifying Cohabitation isn't out yet I can't really draw parallels, but the plot description is pretty similar. In The Life of the White Fox, the fox was holed away in a cave for almost 1000 years, and right before he was able to ascend, dramaland happened and somehow the main girl ends up with his pearl in her body. They end up living together and falling for one another as they attempt to get the pearl out.

Another T-drama starring Joanne Tseng. Includes lots of high school flashbacks to show the central romance developing. Also balances storylines between professional and family life, with a lot of cute family scenes.

Another Taiwanese drama with a haters-turned-lovers central romance. Also, there's some similar professional intrigue (including a hostile takeover) but it's at a travel agency instead of an ad agency.

Go Go squid is an e-sport drama. Really liked it because with friendship is how every dream can become true. This drama is also similar to "The King's Avatar" it is also about leading a team to victory.
YOU WILL REALLY LIKE IT. At first I just tried it out because of curiosity, didn't know it was going to be so good. Also the osts are the best, super inspirationals.

-In both dramas, Wallace Huo is the male lead, just with a completely different character.
- But in both dramas, I felt like both couples were willing to do anything and everything for each other. They were both willing to sacrifice everything to save each other time and time again. Although in Journey of Flower, the leads do everything to make sure that the latter doesn't find out and in Perfect Couple, they find out real fast somehow.

- In both dramas, the female leads meet in the beginning of the story and due to circumstances, the female lead uses the second female leads' identity.
- both leads ended up engaged or married to the male lead
- in both, the second female lead reappears and here is the difference, in Perfect Couple they become good sisters and help each other, and in Destined to Love You, it was different.
- in both dramas, it had a feeling of no matter what happens, the leads will still love each other which lives up to the names Perfect Couple and Destined to Love You. They each have a theme song that reflects that feeling for me.
- both had a good amount of martial art scenes
- both female leads are pretty good at martial arts and can kick butt.
- in both dramas, the male leads were hobos at some point in the story.
- the screenwriter for both is Tong Hua so no wonder they had a similar feel for me.

This is for the people that like to cry to movies

Summoned by an unexpected phone call, an elderly woman visits a cottage she used to live in as a child. She begins to recall her memories of a boy she knew 60 years ago.
The young Suni and her family move to a small rural village in Korea. There, they encounter a strange ‘wolf boy’ hiding under a bush and take him in out of pity. Bothered by his wild eyes and feral behavior, Suni teaches the boy to wait patiently before a meal, put on clothes, and read and write the alphabet so that he can one day live like other human beings. Slowly, the boy begins to develop feelings for Suni, the first person to ever show him affection. Then one day an unexpected threat exposes the boy’s deadly bestial instincts, and in an instant, he becomes the subject of the villagers’ fears. Desperate to save the life of the boy who risked his own to be by her side, Suni leaves him with a promise: ‘Wait for me. I’ll come back for you.’

Both dramas feature a FL and ML that have an arranged marriage, before meeting face to face they both refuse to get married, ending up with one of the leads marrying another (In TLOJY the ML marries her sister and in PS the FL marries a general).
But the two fated leads later meet and begin to fall in love without knowing the others true identity, in these parts of the dramas the FLs conceal their identities (In TLOJY the ML also hides his identity though).
Once the couple realizes their lovers true identities and their true feelings for each other they go through a lot of struggles so that they can marry each other, after a lot of failures they finally have their happy ending :)

Both had a certain focus on dreams; on the main hero's conflicts about having given up on their dreams and later strive on to reclaim the dreams they used to have. Both movies also had another Ultraman being brought onto their worlds by a different party.

Similarities

(Pretend to be someone)
-Adorable supporting character
