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 :)

The romance part in this drama is giving a same vibe where the female lead chase the male lead first. In go go squid, the female lead is more intelligent and capable. If u love playful kiss, please give try to watch this drama!

The storyline almost the same because both of this drama and movie was adapted from manga called "Itazura Na Kiss". Jiang zhi shu and yuan xiang xin in this drama have more chemistry and their chemistry is one of the best in Asian Drama. Then, in this drama Jiang Zhi Shu show more humanity and warm toward xiang xin. If u want to see more details about their relationship, go watch this drama!!! It worth ur timeee. And this drama is part 1. If u want to watch their continution about their life after get married, then watch "They Kiss Again".
