Just for their idol Song Ji Hyo, they went "ugly" for a night.
Five local female fans of the Korean star turned up at the Emergency Couple Fan Meet on Friday in a state they claim was their biggest nightmare - without make-up.
But there was a method to their madness.
Bearing placards that read "Look Here, No Make-up. Choose Me!", the group was hoping that their make-up-free gambit would catch the attention of their favourite star, so that they would be picked to go on stage to play games with her.
After all, Song, 32, is renowned for her bare-faced beauty. She often appears on Korean variety show, Running Man, where she is a cast member, au naturel.
"We came up with this idea because Song Ji Hyo looks so beautiful without make-up and in an industry where looks are so important, she doesn't care if people see her in her natural state.
"That sends out a powerful message," said cafe owner Soh Min Si, 30, who declined to have her make-up free group's picture taken.
Ms Soh and her four friends, all self-confessed make-up addicts, were at Kallang Theatre for the fan meet with Song and her Emergency Couple co-star Choi Jin Hyuk, 28.
In the hit Korean drama, the duo play a divorced couple whose paths cross again when they work at the same hospital.
Emergency Couple airs every Monday and Tuesday at 10pm on channel M (SingTel mio TV CH 518 and StarHub TV Ch 824).
On Friday night, the crowd at the Kallang Theatre, about 1,600 of them, screamed wildly the moment Song and Choi appeared on stage. While Song was outgoing and bubbly, Choi appeared shy, seemingly overwhelmed by the fan's passion.
When asked how she maintains her looks, Song said: "I eat well... I also make sure I wash my face very thoroughly. This is all about going back to basics."
Song and Choi were then asked to pick fans from the audience to go on stage to play games with them.
Many eager fans jumped up and down, waving their arms, posters and whatever they could get their hands on to get the pair's attention. The lucky ones ended up playing a ball game and re-enacting scenes from Emergency Couple with Song and Choi.
In one particular scene, the fan's task was to put a stethoscope in their chosen celebrity's ears, while placing the other end on their own chest and then profess their love for them.
GAVE HER ALL
One fan shocked Choi when she dragged him by the arm dramatically and acted the scene out, no holds barred.
Choi said later to loud laughter from the audience: "I was so shocked (at her behaviour) I hit my teeth on my microphone!"
Unfortunately for Miss Soh and her make-up free friends, baring their faces was not enough to catch Song's attention.
Marketing manager Louisa Tang, 32, who was part of the group, said that their sacrifice was still worth it.
"When we washed off our foundation and mascara after work, we looked bad, it was scary.
"My husband has never even seen this 'ugly side' of me. It took a lot of guts to make our way here and sit through this."
Ms Tang added: "But you know what, although we didn't get picked to go on stage to play games with Song Ji Hyo, just seeing her and being brave enough to do this was strangely very empowering."
