Through the two hours that she watched K-pop group Girl's Day perform on stage on Friday night, wheelchair-bound cerebral palsy patient Sara Hajar Thabar, 22, could be seen clapping her hands and laughing happily.
Sometimes, she would put her hands on top of her head to make a "heart" shape.
She was just one of the 1,500 enthusiastic fans who turned up at the popular girl group's first performance here in Singapore. It was their first solo concert outside South Korea.
Even though she was wheelchair bound due to her condition, Ms Thabar said she made the two-hour trip alone from her home in Hougang because the band are her no.1 idol. She paid $188 for her ticket.
She says: "I have liked them ever since they debuted in 2010. They are like the sunshine that brightens up my day. I call them my happy viruses."
The quartet, known for their mostly sweet image, were giving the concert as part of the KStar Fanfest at Marina Bay Sands convention hall. Held on Friday and Saturday night, Kstar Fanfest is the grand finale of the annual two-month Korea Festival Singapore 2014, which is in its second edition this year. It is organised by Sphere Exhibits - a subsidiary of Singapore Press Holdings - and CS Company in conjunction with the Korean Embassy and the Korean Tourism Organisation.
The concert was attended by Korea's ambassador to Singapore, Suh Chung-ha.
It was hosted by Youtube personality Dee Kosh and televison host Evelyn Kuek. Also present were 50 or so members of the group's informal fan club here and the three Singaporean administrators of their official international fan site, Girl's Day Daily.
The group - comprising members Hyeri, 20, Minah, 21, Sojin, 28 and Yura 22 - opened the concert with their hit 2013 song, Expectation. They were togged out in midriff-bearing printed tops and short skirts, then changed into bright red outfits halfway through the concert.
They also belted out their latest hit songs such as Something and I Miss You. In between, they played games and interacted with their fans.
Even though they sang and spoke mostly in Korean, sometimes through a translator, that did not stop the largely young crowd from having a good time.
They jumped at every opportunity to interact with their idols, raising their hands enthusiastically and yelping with joy each time their stars singled them out to go on stage.
Games such as charades were played. Some fans were invited on stage to ask their stars questions on their ideal men and where they would like to go with their boyfriends if they were to have one.
After the concert, fans who paid $238 to qualify as a VIP also got to troop on stage to high-five their stars.
Polytechnic student David Chin, 20, was one of them. "Their hands felt warm. I have been their fan since 2011 but this was my first time seeing them up close. It was very surreal."
