Park Bo Young
In 2019, Ahn Hyo Seop and her senior Park Bo Young got married in the TV series Abyss. The story revolves around the character Go Se Yeon (Park Bo Young) - who was revived thanks to Abyass. Later, she meets Cha Min (Ahn Hyo Seop) - an old classmate and they decide to go together to solve the hidden secrets.
Because co-star Park Bo Young has a "young, un aged" face, Ahn Hyo Seop and her senior do not have much age difference when standing in the same frame. The two actors get along well and interact sweetly in the film's love scenes.
Lee Sung Kyung
In the list of "screen lovers" of Ahn Hyo Seop, it is impossible not to mention Lee Sung Kyung's name. The two had a good collaboration in The Doctor part 2 (Dr. Romantic 2).
Specifically, if Ahn Hyo Seop won the hearts of viewers through the character Seo Woo Jin - a cold guy with the desire to overcome psychological obstacles to become a good doctor and help those in trouble, the role of Cha Eun Jae, being straightforward, upright, and professionally devoted, also helped Lee Sung Kyung enter the top 10 most favorite female characters of 2020.
On screen, although Ahn Hyo Seop and her 5-year-old senior did not have many kissing scenes, the good interaction between the duo still received many compliments. The sweet and romantic long kiss of the two in the final episode finally satisfied the audience's expectations.

Kim Yoo Jung
In 2021, Lovers of the Red Sky starring Ahn Hyo Seop and Kim Yoo Jung caused a stir on Korean screens as soon as it first aired.
The story revolves around Hong Cheon Gi (Kim Yoo Jung) - a genius painter, the first woman to work at the Royal Academy of Fine Arts. One day, she accidentally meets the blind man Ha Ram (Ahn Hyo Seop) - an officer at a royal unit in charge of astronomy, geography, and meteorology and is immediately attracted to him.
On screen, the combination of the "famous goddess" and the handsome man brings viewers a new feeling but no less sweet on the outside. In addition to compliments about their beauty, the couple also delighted fans with their role-playing acting.
It is known that the film ended with a happy ending for the same character duo with a rating of up to 10.4%. Many audiences expect "Red Sky" to have a part 2 to continue to witness the story of Cheon Gi and Ha Ram.
