Cosmetic Playlover

Main leads in both dramas are coworkers and one of them is slightly envy of the other for being better at job.
(P.s: the color pallette of the posters are kinda similar ?)
Enjoy

Teiichiro married his wife, Sachiko, and succeeded his wife's parents' company, Ishino Clinic, in Kanazawa. Although the doctor is reputed for his straightforward work, he has been hiding a secret from his wife for three years. He has been having an affair with a college student, Umezawa Tomohisa. One day, a detective investigating a murder case comes to Teiichiro. A man named Sugiyama, arrested for alleged murder, claims his alibi is that he had met with Teiichiro at the time of the incident.

Both dramas have similar vibes, where the male lead is a little jealous and domineering.
On the other hand, in both dramas the other male protagonist is more shy and adorable

Ootani and Tachibana have been inseparable since high school. Now that they're in college, they live together, they're happy and everything seems perfect. But their little world is disrupted when they meet an old high school friend, Yuki, who seems to have a crush on Tachibana, making Ootani feel jealous and insecure. Will Tachibana really choose him over a pretty girl?

Very different series however one thing they seem to share is the love.

Boht leading couples talk things out and communicate. They’re also very accepting and try navigating in society with their target-of-affections being uncommon.

CPL is about 2 people in the work force who strive to succeed while various obstacles block their way. People, career, mentality, self-doubt, jealousy; they are conflicted with several moral dilemmas however they continue to proceed through the treacherous waves hand-in-hand.

ITWY otherwise known as KNKSM is about 2 high school kids who end up falling in love. One kid fears that other kids his own age will not accept him for who he is so he hides his sexual orientation and turns it into a joke. The other kid has many responsibilities because of his family situation but as an honest and bright kid, he just can’t seem to leave the insecure kid alone.

Honestly I love them both and I just want more people to also enjoy these two dramas.

Similarities
- ADORABLE pairing
- the relationship starts off pretty quickly in the first episode, then we follow along as they fall more in love
- "awkward" lead and "cool" lead make the perfect power couple
- side characters are supportive of the relationship

Differences
- workplace romance versus school romance
- one couple tries to keep the relationship a secret while the other is more open (or at least doesn't deny it when confronted)
