Actor Lee Kwang-soo treated production staff members of the upcoming TV series “The Sound of Your Heart” to a food truck to cheer them up, according to news reports Tuesday.

King Kong Entertainment, the home agency of the actor starring in the series, released photos of a food truck with typical Korean snacks including “tteokbokki” spicy rice cake, “soondae” noodle-stuffed pig intestine and “eomuk” fish cake on Wednesday.

The truck was aimed to encourage the staff, who have been on location for filming until the dead of night, local reports said citing the agency.

“The Sound of Your Mind,” based on the webtoon of the same title on search engine Naver, is slated to premiere on Naver in the second half of this year, and will air on KBS2 subsequently.

The webtoon centers on the daily life of its author Cho Seok, his family and his girlfriend. Lee plays the part of the cartoonist, while Hani of EXID will play his girlfriend. It was one of the longest-running and most popular webtoons in Korea, with more than 5 billion hits and 10 million comments by December 2015.
