Actor Lee Joo-been talked about her chemistry with Ahn Bo-hyun of Spring Fever.
Lee Joo-been held a series finale interview for the tvN Monday-Tuesday drama Spring Fever (writer Kim A-jeong, director Park Won-guk, planned by CJ ENM STUDIOS, produced by Bon Factory) on the 13th at a café in Cheongdam-dong, Gangnam District, Seoul.
Spring Fever is a drama about a teacher Yoon Bom (Lee Joo-been), who faces chilly winds, and the man Seon Jae-gyu (Ahn Bo-hyun), who has a burning heart, depicting a hot pink romance that will melt frozen hearts on a spring day. As of the fourth week of its broadcast it recorded a cumulative 410 million views, achieving one of the highest results among tvN Monday-Tuesday dramas aired after 2025, and episode 12 recorded a nationwide average 5.7% viewership on paid platforms combining cable, IPTV and satellite (based on paid platforms combining cable, IPTV and satellite, provided by Nielsen Korea).
Spring Fever concluded its grand finale with episode 12, which aired on the 10th, and Lee Joo-been delivered excitement by giving a passionate performance as Yoon Bom. Adding a poignant sadness to her distinctive urban and sophisticated image deepened the character, and Lee Joo-been proved she could perfectly handle not only bubbly or aloof images but also traditional melodrama and lyrical drama genres.
Lee Joo-been, who shared her thoughts on the finale, said, "Spring Fever has ended, and I feel both regret and a little wistfulness. It was a meaningful work, so I feel good. If viewers enjoyed it, that may be my happiness, and I'm grateful," and cited her "size chemistry" with Ahn Bo-hyun as a reason for Spring Fever's popularity, adding, "Size chemistry was important for the piece, and I thought if I lost more weight my face wouldn't look pretty, so we tried to style it in a comic-like way. In the early episodes there were neutral tones and no makeup, but as it went into the later episodes, I applied makeup to create the feeling of spring blooming, matching the season. I focused on giving it the feel of a romance novel or a comic."
Lee Joo-been spoke about working with Ahn Bo-hyun, saying, "He was very meticulous and responsible. He was an actor who never said 'I can't.' When asked, 'Can you do this?' he was reassuring and gave a sense of stability," and added, "He has very large hands. Mine are large too, so there was no burden when doing hand acting. And he never stopped working out on set. I could tell he was someone for whom exercise was ingrained. He was always above my head, so I remember looking up at him."
She continued, "I was amazed that he paid attention even to those small details. I felt he was an actor who really thinks things through a lot before coming. There was a lot of camaraderie. Although it's a rom-com, there were many physically demanding scenes, so when we accomplished something we felt a shared sense of reward," adding, "This person should have gone into athletics. Had he gone into athletics, he would have been a gold medalist. There were many shots that were not doubles, and he handled them well on his own."
Not only the size chemistry with Ahn Bo-hyun but also the kissing scenes excited viewers. Lee Joo-been said, "It wasn't just standing and hugging and kissing; it was closer to action. I was lucky to meet an actor who could do all of that. When asked if he could lift me and spin me around, he said he'd try, and I thought, 'This works.'"
In particular, regarding the reactions suggesting she was romantically involved with Ahn Bo-hyun, Lee Joo-been laughed and said, "People asked a lot about the co-star from the beginning, but I tell them to stop talking about it. They asked so much that these days they don't ask as much."
