• [2026 ★First Half-Year Review] AI-Assessed Top Drama Couples' 'Compatibility' for the First Half of the Year

How was the 'compatibility' of the couples in the dramas we loved during the first half of 2026?

It is already halfway through 2026. Over the past six months, works that 'instantly erased' (deleted in an instant) viewers' time have inevitably poured out. Especially this first half of the year saw a large number of couples stirring up the living room with particularly sweet 'loco chemistry' (romantic comedy chemistry).

Among them, couples who received intense attention in terms of ratings and buzz include MBC's '21st Century Grand Duchess' (hereinafter 'Grand Duchess') Seong Hee-ju (played by IU) and Prince Lee An (played by Byun Woo-seok), SBS's 'A Wonderful World' Shin Seo-ri (played by Lim Ji-yeon) and Cha Se-gye (played by Heo Nam-jun), TVING's 'Yumi's Cells 3' Kim Yumi (played by Kim Go-eun) and Shin Soon-rok (played by Kim Jae-won), JTBC's 'Everyone Is Fighting Their Own Worthlessness' (hereinafter 'Mojamussa') Hwang Dong-man (played by Koo Kyo-hwan) and Byun Eun-a (played by Go Youn-jung), and TVING·tvN's 'The Legend of the Army Chef' (hereinafter 'Chwisa-byeong') Kang Seo-jae (played by Park Ji-hoon) and Jeong Min-a (played by Jeon So-young). All the actors who played each role were figures who ranked in the top tier of buzz rankings during the broadcast period (based on Good Data Corporation's Fundex).

So, how high is the 'compatibility index' of these couples as analyzed by AI (artificial intelligence) Gemini? We revisited the top K-drama couples that heated up the living rooms this first half of the year through their compatibility.

According to AI analysis, the couple with the highest compatibility index was Shin Seo-ri and Cha Se-gye from 'A Wonderful World'. Analyzed as a 'spicy, sweet, and fierce compatibility that ends in a redemption narrative after stabbing and biting each other', they achieved a score of 98%. It was praised for offering the most perfect catharsis of the first half of the year, combining a narrative structure where a woman betrayed by past power is redeemed through a modern power holder with fierce tick-tock banter.

Furthermore, in terms of MBTI (Myers-Briggs Type Indicator) compatibility, 'ESTP' Shin Seo-ri and 'INTJ' Cha Se-gye were analyzed as having a 'destructive synergy compatibility that serves as each other's brake and accelerator'. Although their tendencies are polar opposites and they often growl at each other, it is explained that they are the ultimate partnership where the brain and limbs fit together most perfectly in front of the common goal of 'survival and victory'.

Yumi and Soon-rok secured 2nd place (95%) as a 'well-made stable-type compatibility'. This couple demonstrated 'mature adult love' in that Yumi's inner cells no longer felt anxious and found peace. The core of the narrative was Soon-rok, who strictly adhered to the rule of no office romance, meeting Yumi as an exception and breaking his principles. Yumi felt respect in Soon-rok's attitude of guarding his boundaries, while Soon-rok found solace in Yumi's sensitivity. Both became the most ideal 'stable-type couple' through their maturity to consider each other rather than being swayed by emotions.

The MBTI compatibility of 'ISFP' Kim Yumi and 'ISTJ' Shin Soon-rok emerged as a 'stone bridge compatibility' that slowly seeps in, providing perfect stability to an anxious mind. Although the beginning was somewhat cautious as a meeting of a steel wall and a defensive wall, they perfectly respected each other's private lives and homebody tendencies, ultimately meeting a peaceful and mature happy ending with no fatigue in the real world.

In 3rd place were Seong Hee-ju and Prince Lee An, showing a comprehensive compatibility index of 92%. The 'mutual complementarity of a stubborn realist and an ethereal romantic' earned them a high score. Seong Hee-ju chose Prince Lee An as her 'most precious weapon', but as the narrative progressed, they showed the epitome of 'business partners and soulmates' who perfectly substituted each other's deficiencies (class barrier vs. royal loneliness). Because they possessed completely opposite deficiencies, Hee-ju's bold advance became a stimulant for Lee An's life, and Lee An's gentleness melted Hee-ju's thorny heart. The narrative that developed from a business relationship to the only bond where they risk their lives was highlighted as attractive.

In the MBTI compatibility analysis, 'ENTJ' Seong Hee-ju and 'INFP' Prince Lee An were also evaluated as having the 'most ideal complementary relationship'. It was analyzed as a gear-like relationship that fits together perfectly both narratively and in terms of tendencies, filling each other's deficiencies 100% without intruding on each other's worlds.

Hwang Dong-man and Byun Eun-a ranked 4th with a compatibility index of 85%. This couple drew attention as a relationship that absorbs and comforts each other like a sponge with just a single word or glance. Although the dramatic romantic tension was somewhat low, they were a couple that stood out for their deep empathy and emotional bond. The relationship between Dong-man, a perennial aspiring director struggling with self-loathing at the bottom of life, and Eun-a, a planning PD groaning from burnout, was not flashy but left a heavy resonance. Thus, they were analyzed as having a 'Soul-bound compatibility' where each becomes the world's only shelter for the other.

The MBTI compatibility of 'INFP' Hwang Dong-man and 'INFJ' Byun Eun-a appeared as a 'mirror-like healing compatibility where they look into each other's souls without speaking'. Although there were no sparks that trigger dopamine, they established themselves as the kindest redeemer couple in the world, perfectly absorbing and healing each other's wounds like a sponge.

In 5th place were the 'Rubber Shoe' couple Kang Seong-jae and Jeong Min-a, recording a comprehensive compatibility index of 78%. In the closed and strict space of the military, Min-a is the only connection to the outside world and a place of rest for Seong-jae, who is writing a legend through 'cooking'. Unlike the original work, Min-a was adapted as an intern reporter covering the military and Seong-jae's reliable female friend, unexpectedly capturing a fresh youth romance narrative. Due to the genre characteristics of military and cooking fantasy, the romance narrative did not come to the forefront, but Seong-jae's massive growth story played a significant role as a pause, bringing fresh excitement.

The MBTI compatibility of 'ISFJ' Kang Seong-jae and 'ENFJ' Jeong Min-a was analyzed as a 'healthy and refreshing helper compatibility'. As a silent guardian who cooks (ISFJ) and a passionate reporter who spreads his value to the world (ENFJ), they became a 'flawless' youth couple.
