Actor Lee Jin Wook and ZE:A member Hyungsik's text is becoming an issue online.

In the photo is the capture of Lee Jin Wook and Park Hyung Sik, who are making their appearances in tvN "Nine."

On March 19 Lee Jin Wook texted Lee Jin Wook "Our Hyung Sik is so good looking! Always fighting! When I see you on screen I'm very proud that you are playing the younger version of me." To this, Hyunsik had replied "I am more honored. I am so happy to be playing the young you. I love you."

An associate of "Nine" stated "Lee Jin Wook is kindly teaching Park Hyung Sik acting on set. They are expressing much love for one another. Park Hyun Sik is also following Lee Jin Wook pretty well."

Watch them both on Nine: Nine Time Travels on Hulu and see if Park Hyung Sik is indeed learning well from Lee Jin Wook.
