Both Kidnapping Game & g@me are adapted from the same novel by Keigo Higashino, The Name of the Game is a Kidnapping

Both are office dramas about bad bosses and hard working environments. While Feel Good To Die is a fantasy genre both are comedies

both Kkondae Intern and Search: WWW are office dramas and both main leads work for the rivaling company of their former work place

the 1st ep of Kkondae Intern had the same mistreatment/bullying by the senior in the workplace as To Each His Own

They're both cute & hilarious variety shows hosted by the main lead of their own series. "TayNew Meal Date" a food & travel show hosted by Tay and New, and "Friend.ship with Krist-Singto" is a fun adventure & travel show hosted by Krist and Singto.

They're both fun & cute variety shows hosted by the leads of their own series. "TayNew Meal Date" is a fun & hilarious food & (travel?) show hosted by Tay and New. "Off Gun Fun Night" is a cute and funny talk-show hosted by Off and Gun.
You can watch both of them on the official GMMTV YouTube channel^^

Same male lead with Contract Relationship and Rich Man/Poor Woman.But this drama is so much better than Kon La Kop Fah.
Both male and female lead have great chemistry in this.
In this also male lead is misunderstood and gets jealous but Female lead is lot more understanding and supportive in this one.They both are always their for each other.
Second leads love story is adorable too.
Definitely worth a watch and much much better than Kon La Kop Fah.

Both females found themselves having little time to become mothers and actively start searching for a candidate to be baby's father.

Both movies span from junior high/high school till they're adults. Ultimately the leads drift apart due to a quarrel and reunite bcos the female lead is getting married.

Both depict the hard life of royalty, with traumatized crown prince/emperor who strives to be filial toward their parent; they are haunted by their childhoods and their relationship with their mother and it guides their decisions as adults

Very similar plots, the female lead is logical and uninterested in the male lead at first. Both also take place in business environments and deal with memory loss.

Immediately thought of this while watching the other. Girl falls for guy who was part of band who broke up.

-Both male leads go prison when they were innocent
-Both escape from prison with someone's help .
Although with rugal its an ally, but doubtful victory its enemy.

-Both male lead go to prison although falsely charged, because of threats of harming someone close to them, if they don't admit the crime
-Both escape from prison after years
