Krystal shared through SMTOWN's official Facebook, "I am eating the delicious food you have all sent me on the set of my drama 'Heirs' well! Please show lots of love for 'Heirs'~"

In the BTS photos, Krystal proudly stands in front of her fanmade banner which parodies a line from 'Heirs' and reads, "How can I not give her delicious food? She's pretty...", and also shows her dressed in her uniform while looking out the window at the beautiful courtyard of Jeguk High School.

Krystal has been receiving positive reviews for her English skills, transparent character, and her romance with Yoon Chan Young (CNBLUE's Minhyuk) as the lovable Lee Bo Na. Catch her on 'Heirs' every Wednesday and Thursday!
