My Sweet Mobster

The female leads in both dramas cohabitate with a group of guys who are also pretty rich.
Both of the male leads have a secret that they're trying to keep from the FL. They ML also falls first but tries to act non chalant about it.
The second FLs are very bitchy to the FL but they're also minsunderstood.

The comedy aspect of these two make them stand out.
The male leads are equally sweet and totally wrapped around the fl's fingers

Well, definitelly MSM is a more lighthearted drama, HOWEVER, both dramas have mobster main leads and have also incorporated humor in their plot.
Sooo if you are in the mood for such a drama,you should check it out. I will put more details when it ends as I will be able to compaire and contrast

Senagaki Isaku will be a first-year high school student starting in spring. Her grandfather is the third head of the Senagaki group, a yakuza organization, so she is feared by those around her. However, starting from spring, she hopes to make normal friends and normally fall in love. She is admitted into a high school further from her hometown, however, the overprotective young head of the Senagaki group, Utou Keiya, (26 years old) falsifies his age and enters the school with her through a backdoor admission…?! Keiya proclaims that love is too early for her although Isaku is perfectly ready. In truth, she has held an unrequited love for Keiya for quite some time.

Mobster male leads, male and female leads have past childhood/teen connection. My Sweet Mobster is heavily comedic with occasional serious undertones, Fatal Allure is solely serious and often reads as a soap opera.

When drug dealers attack feisty college student Yuri at a party, she’s saved by Toshiomi Oya, the young boss of a yakuza syndicate. Despite her obvious attraction to him, she convinces herself that she’s not in the market for a bad-boy type. But when they meet again, she finds herself irresistibly drawn to him—kicking off a steamy and dangerous love affair that threatens to consume her, body and soul.

The greatest love in Yakuza BL history. A devoted young boss x a member burdened with a secret mission; what is the destination of their journey together?

The young boss Kataoka, who is deeply compassionate and has a strong sense of chivalry, is loved by many members. However, due to a certain incident, he is ordered by the family head's biological son, Kiriei , to go into hiding until things calm down. The one entrusted with taking care of Kataoka during this time is the member, Odajima, who had previously served as the family head's aide. Odajima takes on the role of driver and assistant, and sometimes handles sexual needs, carrying out his duties without emotion. Yet, within his heart lies a 'hidden mission'—he has been given strict orders by Kiriei to 'kill' Kataoka, who is a nuisance in the succession struggle.

Childhood friends
Gangsters
Animal lovers
Opposites Attract
Calm and Badass Male Lead
Gives the same vibe but in a different day dimension.

The ML is sweet even though maybe at first you might assume he is a bad guy. The FL is a bit different as she isn't as up beat as the girl in my sweet mobster but I think it works since the guy is the up beat one in this drama.

Both Undercover High School and My Sweet Mobster have very similar vibes.
They both have action and are rom-coms.
The main leads knew each other when they were younger, and then later reunite, in both of these dramas.
They both have a group of hilarious side characters (Main Lead's friends).
Both share OSTs by the same artist (Kim Pureum).

My Sweet Mobster leads first starred alongside eachother in Save me 2! Their relationship there was lovely, which is why I've been long anticipating their reunion here!

Both MLs own a meat-producing company and the workers at the company kind of give the same vibes in both dramas. The three frogs restaurant scene in Dali reminded me a lot of the scene in one of the early episodes in MSM where they are at the fair.

These two drama hve similarities in:
-Childhood friends to lovers
- female lead gets unemployed
- male lead runs a company
- cute second couple
And overall they are both sweet romcom to enjoy watching

The story follows a desperate housewife who signs a contract with a cold and sadistic mafia boss, turning a relationship of domination into love.

Both dramas tell stories about complicated relationships. "My Dearest Nemesis" seems to be about people getting over bad things that happened to them and growing as people. "My Sweet Mobster" seems to be about a man trying to be good after being bad. So, if you like shows with people who have old relationships and change a lot, or if you like shows about childhood relationship, you might like both of these dramas.
