The Sound of Your Heart (Korean마음의 소리; also known as The Sound of Your heart, Sound of Heart) is a South Korean webtoon series written and illustrated by Jo Seok.[1] The webtoon was first released on the Naver Webtoon internet portal in 2006. In 2007, the first print volume was released and The Sound of Your Heart was adapted into a TV series of the same name in 2015.[2][3]


On December 17, 2015, the 1,000th episode of The Sound of Heart was posted on Naver. Since Jo started posting his webcomic on Naver, views averaged 5 million per update, a total of over 5 billion views. The Sound of Heart is the longest running South Korean webcomic.[4]

When Jo got married in 2014, he did not have a wedding ceremony or honeymoon trip because he did not want a lapse in his update schedule. In 2015, Jo earned about ₩78,000,000 per month (approximately ₩936,000,000 per year).[3]


The Sound of Heart features author Jo Seok as the main character.
