Secret Garden (2010)

Both are written by the same person and the story development is very similar.

Both are about really strong wealthy male leads that are simply combobulated by the thought of them falling in love with a... how'd you say... peasant? Lol jk

Sun Fan is a stunt double who dreams of becoming a big star. When he suspects Fang Zi Hao, a famous singer, trying to steal his girlfriend, he beats the living daylight out of Fang. His attack against Fang incurs the wrath of Yu You Tong, who is a die-hard Fang fan. She mobilizes the fan base to attack him online. But to her dismay, instead of ruining him, the internet makes him an overnight star as people praise his skillful fighting moves. Because of one fight, four strangers suddenly become entangled in more ways than one.

The leads switch bodies and look for ways to come back to their original bodies.
In the secret garden the Leads fall in love, but in Kamisama no Ekohiiki the leads don't fall in love but cooperate to return to their original forms

Both are from the same writer and share the same type of humour and witty dialogue

Body-switching romantic comedies never get old! It's hilarious to see hot actors like Gong Yoo and Hyun Bin behave like they're someone else trapped inside their body.. and the parallels to the plot are naturally many.

Both of the dramas have that amazing romance in it, and strange sequence of events that results in them swapping bodies.

Both have a hot, young CEO that have some crazy personality. the Ceo action and personality both make u laugh n rolling on the floor at how cute n ridiculous they are

In both dramas, the protagonists are stunt doubles who dream of becoming a star someday.
The problems start due to their skills in martial arts: in Secret Garden, Ra Im calls Joo Won's attention; and in Because of You, Sun Fan draws the attention of netizens.

it's not a fantasy but gives the same nice feeling you get during watching a Korean rom/com

Both of these dramas have a lead character who falls in love and it turns their narrow world upside down. It also makes for great comedy to watch the confused and wholly selfish chaebol become a huge, hilarious mess and eventually a better person for the person they love.

Just because both are my most favourite out of all k-shows. Also they have awesome story line and beautiful casted couples.

You could say both male leads act mental at times but make the drama so, so funny at times!

Both shows are lovable feel good romantic comedies that most people will want to watch again and again. Though 30b17 doesn't have any evil characters, just very tough traumatic circumstances that the main couple have to overcome. Both have male leads who suffer from PTSD due to a traumatic accident that they blame themselves for. Both couples are connected through a childhood accident but meet unaware of this fact as adults. Both male leads are perceived by everyone around them as odd, antisocial and harsh, but eventually they learn to soften their behavior due to their love for the plucky female leads. Both female leads are orphans who have to go through a lot of hardships because they are alone in the world without family support and end up creating a new family with the men they meet. I love Shin Hye Sun as much as I love Ha Ji Won as an actress. Though Ha Ji Won has had many more shows where she's the lead, Shin Hye Sun makes me root for her the same way Ha Ji Won does and I end up looking for other shows of hers to watch in the same way.

A body swapped story between older woman & a younger man. For who like comedy genre this drama is a must watch drama. Hyun Bin toooo adorable in this drama.
