Perfume (2019)

Both dramas are about one of the leads falling in love with the other when they were younger and being reunited later on after the female lead has gained/lost weight. Her changed appearance also leads to mistaken identity/not remembering the other from before.

-The males leads both have anger issues
-(LITTLE SPOIL) There's a similar scene where the male lead gets jealous while the female lead talk to another man so he throw water to him
-The same type of humour
- sorry for this one but there's also that one annoying ex girlfriend ?
Tho only similarities are the type of romance, it has no murder but the males leads have a traumatic past

When brash, street-smart orphan Oh Dae San, who makes his living copying designer fashions, and the apathetic grandson of the fashion empire Lee Joon Hee meet by chance one day, the two men realize that they look exactly alike and in that, they see a chance to set each other free. Pressured by his stepbrother and stepmother to give up his rights to his grandmother's business, Joon Hee wants to investigate his family background in secret, so he decides to hire Dae San to distract attention for a day. Dae San, initially resistant to the idea, has become involved in the financial difficulties of the daughter of a recently-deceased friend and will do anything to help her. What starts out as a one-day deal turns into something deeper and more complicated, as secrets arise about the real connection between them

Han Se Kyung is a young woman with a very positive character. Her motto is "effort will take me as far as I want to go". She wins many designing contests and finally joins a clothing company. But, at work, Han Se Kyung does errands and chores rather than design. Meanwhile, the wife of an upper management employment at the clothing company humiliates Han Se Kyung. The wife is actually a former high school classmate of Han Se Kyung who didn't do better than her in school. This makes Han Se Kyung look back on her life.

Not exactly the same but they seem to have similar messages and character set-ups
- Both ML's were overweight in their younger days leading to self image issues
- Both ML's face psychological issues because of the FL's past rejection
- Both drama's feature a boss/employee relationship

If Private Life and Crazy Love had a love child... you would get the fantasy drama Perfume (2019)!!!
In both dramas the leads have a hate-love relationship. The ML's have a past trauma they don't share with others until the FL comes along.

Both have a fantasy element that help the female lead to change appearances for a period of time using a perfume or a coffee in the other.

Both the shows have a Male leads where they have severe multiple phobias and a Female lead to help the other in a certain way.

Both have a strong mother female lead that enters the workforce and protects their precious but bullied daughter. This is the main plot for Angry Mom however Perfume's main plot revolves around a love story.

The dramas are different but for some reason, they have the same vibe. The female leads personalities and the (kinda) love triangles are similar. They both are enjoyable and funny. Even though User Not Found was about students who switch identities and Perfume is about an adult who gets younger, it has the same "pretending to be someone I'm not" storyline

* In both shows FL appearance changes due to stress and eating disorder. (they are overweight)

* ML hires FL to do his chores.

* Both shows are related to entertainment industry.

A body swapped story between FL older woman & SML older man. For who like comedy genre this drama is a must watch drama. Matsuzaka Tori toooo adorable in this drama.
