Love Your Enemy

Leads who knew eachother as kids reunite in a school setting. Female leads are both gym teachers and male leads are both rich businessmen. Bickering dynamic between them continues from childhood into adulthood all as romance ensues.

I’m not 100% sure why, but I get similar vibes from these two. Maybe it’s the childhood connection and the lingering feelings. ML in both also resist being like their father and want to make things right.

Both leads were childhood friends, where both of their families were tangled in the past. At first, ML hated FL and gradually fell for FL. As they grew up, they were estranged and reconnected years later.

This drama also explores the concept of ex-lovers reuniting under awkward circumstances. Just like in Love Your Enemy, the characters are forced to confront unresolved feelings and grow emotionally, while navigating a mix of tension and humor.

This drama explores the theme of ex-lovers reuniting after years apart, delving into unresolved feelings and the complexities of rekindled relationships.

Somehow reminds me of this drama. May be it is the shared premise of two high school classmates who were considered enemies reunite after years.

Both dramas revolve around lovers who have a complex history. In Fireworks of My Heart, the leads were childhood sweethearts who parted ways due to misunderstandings, only to reunite as adults. This theme of rekindling old feelings mirrors the dynamics in Love Your Enemy.
The protagonists in Fireworks of My Heart work in high-pressure, life-saving professions (a firefighter and an emergency doctor), which often brings them into tense, challenging situations. Similar to Love Your Enemy, this creates a dynamic where professional duties intertwine with personal emotions, blending conflict and affection.
Both shows explore the characters' emotional journeys, showcasing how they evolve through their shared struggles and rediscover their feelings. The emotional depth and slow-burn romance appeal to viewers who enjoy layered storytelling.

Both are modern romance korean dramas. Both dramas also have same premise as two childhood friends/lovers reunited when they become adults.

Both are enemies to lovers. The vibe is similar and the characters energy is really the same. The ML is wealthy and rich, while the FL is strong and independent.

Misunderstanding and they separate
ML originally wants to take revenge against FL but ends up falling for her all over again and chasing her first

Seok Ji Won and Yoon Ji Won, born on the same day with the same name, have been rivals for years. After 18 years, they reunite when Seok Ji Won, now the executive director of Seokban Construction and chairman of Dokmok High School, returns home. Yoon Ji Won, once known as the "Dokmok High School Mad Dog," is a physical education teacher at the school. Both have changed, but their old rivalry reignites as they confront their past and present.

Mature but childish leads!! Competition, and from haate to love relationship!!
The genre and caracters are similar!

Both feature a strong, outgoing FL who butts heads with a male childhood frenemy in a High school setting. Fighting or flirting leads to love.

They are both about high school mutual crushes that are separated by misunderstanding and meeting again after 10 years

Enemies to lovers, past lovers reunited, and tons of bickering. In both the dramas, the male lead takes the initial steps and both have good looking men.
