Itaewon Class

MAYBE CONTAINS SPOILER

in both of them, there is a bad chairman who ruins others life by bribing police, prosecuter or teacher
also the main character suffers from injustice
and the main character tries to destroy bad chairman.
romatism is less than itaewon class but good.

The similarity between these two drama are both of them very inspiring and warm hearted! Both of drama also have taught me about reality of life, did not easily give up and motivate me to move forward even though our life is hard.

The main character interaction also kinda gave a similar vibe where the male and female lead try to understand and heal each other. And the main character also has a huge age gap but it doesn't matter as their relationship will naturally develop :)

If u guys love Itaewon Class, u will definitely love My mister :)

they are both based on the same webtoon. Roppongi class is just the Japanese version of it. A similar story just adapted for the culture of each country.

--both dramas have the main character seeking revenge on an injustice that they faced.
--at the end of the dramas, they both realized that there's more to it than just revenge and that it wasn't as satisfying as they thought that it would be.
--both main characters faced several hardships and adversities before they could become successful and establish themselves

In both dramas, the male leads need the help of the female leads to get their lives together and enter the business world — to rise high enough to take revenge on the ultimate giant of the economic world.

Similarity on the long-term goal that two leads made with each other from their late childhood years.

Park Saeroyi's life has been turned upside down after he gets expelled from school for punching a bully and his father is killed in an accident. Following his father's steps, he opens a pub named "DanBam" in Itaewon and, along with his manager and staff, strives towards success and reaching greater heights.

Both are stories of revenge with competition of two restaurants: one already very famous and influent, but with problems caused by CEO's incompetent and spoiled son; the other new that is a mixture of passion, talent and newbies who don't have anything to do with cuisine, but who learned a lot and became very skilled. In both the protagonists have big age gap.
