Lovely Us (2020)

This really same vibes:
1. Enemy to love
2. Childhood relationship
3. Classmate
4. FL is silly student
5. FL is sassy and cheerful

Both are short, sweet dramas in which the mains are childhood frenemies to romance, and the ML ends up falling for the FL first.

Similarities :
- Both dramas show us main characters' high school life to adult life.
- a group of 5 friends.
- neighbors.
- childhood friends.

Both dramas have a main couple who are childhood friends, now in high school. In both dramas, the ML falls first and harbors a crush for a long time on the FL without her realizing.

Both dramas have a school setting, a similar tone and pacing, and a frenemies/semi-antagonistic relationship between the leads that gives way to friendship and eventually romance.

Similar bond between families and romance between childhood friends..........................................

Created by same production team, director, and writer, it is about friendship, growth, learning and come to terms with one owns worth. However there is dissimilarity as well, while the setting in Lovely US starts from school to their adulthood to their professional lives, here it shows people already living in professional world come to heal and love.

Both series are free from external pressure factors, angst, and scheming but has same nostalgic vibes, melodic style, and energetic core performances.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide
