Responde 1997 (2012)

both the dramas are about a group of friends in school.

Although their approaches are different, both focus on a lifelong close relationships, between best friends of the opposite sex, possibly turning into romance.

As major themes: both are funny, heartwarming stories and feature the main characters growing up and becoming more confident adults.

Other similarities include: featuring high school reunions although at different scales; There is definitely an element of who is the daddy/husband mystery in both although for very different reasons; Both have really cute/inventive title cards for each episode and are 16 episodes, so on the shorter side for dramas

The dramas are both set in the 1990s-2000s. Both feature a will-they, won’t-they relationship between best friends. The FLs are also similar in personality.

Both dramas have a similar way of keeping you guessing on who the female lead will wind up with in the end. I think Reply 1997 does it better though.

Two brothers fall in love with the same woman.

The story lines are definitely different, but both of the main roles are friends since they were young. They know each other's habit and have an undescribed feeling for each other not knowing it was love as they growing up together.

Both are a guessing game. In Reply 1997 you are guessing the husband and in Secret Seven you are guessing the Secret admirer. Both also feature 90s music. Reply 1997 is more serious, while SS is more like a light hearted game.

Both leads are childhood friends. The male lead liked the female lead first. Both female leads are strong-willed and work in the entertainment industry.

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.

Another drama partially set in the past, tha has you guessing what happened to the characters and what led them to their present life.
Reply 1997 and My First Love Is Secret Love are both heavy on nostalgia, abeit they start 11 years apart.

Seo In Guk is a male lead in both shows.

He plays a completely different (but oh so lovable) character.

These shows both made me laugh out loud throughout and are lighter comedies that let you forget your worries and take in the sweet stories.

both have the classic friends to lovers trope and the same leads having 'something' for each other but not confessing because their current friendship might be jeopardized. i dont really know how to explain it but the male leads of both are very similar according to me

Both dramas are about childhood friends who are in love with each other, and both pose in the beginning the question of who the girl is going to marry, and the viewers eventually find out at the end of the drama.

Hilarious, heart warming, and so very relatable. These two dramas share the same breezy and comedic tone, and both dramas experiment and play around with a fresh format with which to tell their story. Reply 1997 perhaps feels a bit more familiar compared to your standard kdrama, while The Lover feels more like a sketch comedy show- think SNL, only more cohesive and consisting of more genres than just comedy. Both aired on less popular networks, both of these dramas have a similar and unique way of carving their way into your heart. (They also both feature gay character(s), which is definitely a notable feature for Korean shows!)
