Seonghwa, a member of the group ATEEZ, has published a special book titled 'Before Sleep,' containing his original poems and essays, in collaboration with Dingo Story.

On the 6th, Dingo released a video for the 'Before Sleep' Seonghwa episode, a representative healing reading content. With a calm voice, Seonghwa recited four original poems he wrote himself based on the emotions he experienced before and after his debut, along with essays based on them, delivering comfort and empathy to fans.

The newly published special book includes two previously unreleased original poems and two essays that were not featured in the video. A total of four poems and four stories have been included in their complete form. His agency, KQ Entertainment, announced that all proceeds from the book's sales will be donated to child welfare facilities.

This collaboration between Seonghwa and Dingo Story added significance as a social contribution activity through donation, while simultaneously delivering sincere messages to global fans through his original poems and essays.
