The members of Girls' Generation can always be seen covering Sunny's ears due to her traumatic experience in the past. She used to live in Kuwait when she was little and had to live through the Gulf War that caused her a lasting fear of loud explosions. She still gets surprised when she hears explosions, for example, the unexpected fireworks on stage. So the members will close her ears whenever there are fireworks on stage. Aw..... They are so caring!!
