The idol star talked about her acting career in a recent interview with Xports News. Out of all the productions she took part, Krystal named 'High Kick' as the most memorable. 

She stated, "I still watch clips of 'High Kick' sometimes. I was 18-19 then and when I rewatch it, I come to think that I was really young then." She added, "It's a production that I filmed for a long time. I still keep in contact with the director. And the director and I have the same birthdays. We have an amazing connection."
