On July 20, f(x)s Krystal posted a photo on her personal Instagram of a coffee truck that actress Park Shin Hye had sent her on the set of Bride of the Water God.
In the caption she wrote, Weve done nothing wrong, a reference to the banner on the coffee truck that reads, Weve done nothing wrong except to look too pretty. Please look after our pretty Soo Jung. Love from Shin Hye.
The two actresses previously worked together on the set of SBS drama Heirs.
