Singer Seol Ha-yoon is releasing a ballad titled "Reason." The song will be released at 12 PM on January 30 through various online music platforms. "Reason" is a ballad that calmly expresses the lingering longing and emotional traces that are not easily erased even after a breakup. It unfolds gently around a calm piano melody, harmonizing Seol Ha-yoon's stable vocal tone with restrained vocals. Instead of elaborate arrangements, a minimal instrumental composition was chosen to maximize the delicate vocal expression and lyrical delivery.

This song was completed based on inspiration from the Japanese film director Shunji Iwai's movie "Love Letter." Emerging composer Lee Seo-young participated in the song, and all instrumental parts were performed by actual musicians to enhance the depth and texture of the sound. Especially, the chorus "I miss you, I can't forget you" succinctly captures the resignation and acceptance of unreachable love, leaving a deep impression.

Since her debut in 2016, Seol Ha-yoon has mainly been active in the trot genre. However, this is not her first challenge in ballads. She already proved her potential as a ballad vocalist through the OST "Flowers Bloom Like the Spring of My Life" for the 2019 KBS2 drama "My Only One." At that time, she received praise for enhancing the drama's immersion with her restrained emotional line and stable singing.

Her agency, TSM Entertainment, stated, "'Reason' is a song that depicts the process of fully accepting and letting go of the pain of a breakup rather than forcibly pushing away those feelings," adding, "You will be able to see Seol Ha-yoon's deeper vocal capabilities and emotional maturity." Seol Ha-yoon is an artist who has consistently proven her solid vocal skills and stable stage manners through broadcasts and performances. She has expanded her activities by communicating with fans through SNS and online content.

The new song "Reason" is regarded as an important work that expands Seol Ha-yoon's musical spectrum. The challenge of the ballad genre is expected to make her musical abilities even more diverse. Based on the vocal skills and delicate emotional expression she has built in the trot genre, she is expected to achieve successful results in the ballad field through this new song.

"Reason" will be released at noon on January 30 on major domestic and international music platforms such as Melon, Bugs, Apple Music, and Spotify. This new song, which showcases a new musical side of Seol Ha-yoon, is expected to receive great attention from fans and the public.
