In a Good Way (2013)

Both are about school life and romance in the 1990s.

Female lead who follows their childhood male friend to another city only to be disappointed by him.
Female lead learns, grows and works on improving herself into a confident individual for her own sake.
Male lead falls in love female lead while helping her.

Again popular guy falls for the unconventional girl,
They grow together in terms of overcoming their weaknesses and finding their path in life and become somewhat strength for each other

Both are about college students:

In a Good Way - centers around a main couple and their college life

Age of Youth - AMAZINGG!! It talks about 5 young women who live together for college, and shows the development of their friendship from strangers who tolerated each other to the best of friends, along with the experiences each character goes through. IMO, I loved Age of Youth more because it also touched based on dark themes, and showed different personalities.

In A Good Way is not a Korean drama (it's Taiwanese), not set in high school (it's set in college), and the focus isn't completely on the romance, but the same theme is at the heart of both dramas: friendships, relationships, and growing up. Both shows are set in the 90s and explore the lives of their characters as they transition to adulthood and go through all the trials and tribulations that come with that period of transitioning and figuring out friendships and relationships. They both portray relationships with incredible realism, fully develop all their characters into real, flawed, multidimensional people (no real antagonists here), and create these day to day slice-of-life portraits that are full of nostalgia and happiness.

Both involve friendship and romance among a group of friends in the 1990s. Both with the theme of youth and things they learnt in the process of growing up (e.g. What they lost or gained while growing up, the responsibilities they will have to take up upon turning into an adult)

The nostalgia feeling. Young shy girl going to college and growing up, falling in love of a friend. unwanted love. Different backgrounds. Friendship.

Both gave me the same feeling, I really recomend them.

Both dramas are feel-good, slice-of-life college dramas. They both follow a group of friends as they enter their first year of college and looks at the struggles and joys that come with friendships, relationships, and college. The characters all seem real and complex.

Both dramas represent youth & their problems in adolescent years. In a good way have a lesson about never giving up on dream much as in WFKBJ.
If you can watch Taiwanese dramas, give it a go!!

Main couples in a both dramas are just incredible cute and vibe of these dramas is similiar.. main girls are in the beginning insecure but with a time they does grow up in a beautiful confident independent ladies...although In a good way is slightly more serious and Boss and me is more romantic and fluffy, it´s still have that simple lovely feel of happiness from the life :)

Although this two dramas have very different premise, they have a lot in common.
- for starters they both meet on campus and the romance starts there
- secondly both leads have an activity they enjoy which brings them together and even closer, in the case of love o2o, it video game but in a good way, it's treasure hunting.
- in both drama, both leads have a group of very fun, very interesting, very loyal friends who are always there for them wether it's to educate them about romance or just tease them about it.
- in both drama, although the female lead has an admiration for the male lead for longer, it's the male lead who starts having romantic feelings first and who goes after the girl first indirectly by talking online wether it be with the game characters or online chatting and she kinda falls for the online character before she realizes who he is and then he goes after her in person too.
- in both, the male lead is smart, and athletic and is the most sort after guy in school, they also both play basket ball and are from an influential family. Either professors/writers/archeologist/historian or politician.
-in both cases, the male lead tries to make a name for himself away from his parents although in a good way, the parents are not supportive while the parents in love o2o let do what he wants.
- both female leads aren't ditzy and helpless but are very intelligent, very good in the activity they share with the male lead, independent, and can stand up for themselves and for those they love often pulling the male leads and his friend into their shenanigans,

I bet I could find more similarities but I m going to stop here, but I would advice to watch both dramas if you haven't because they re both interesting.

Both have a similar vibe and feature a group of friends working together and fighting toward a cause. You see them transition to adulthood. In A Good Way is more about their university days while Youth Power is more about post graduation.
