When a warm voice is added to a song, the emotion comes across twice as strongly.

It is because of his unique, heart-stirring vocal tone and tender sensibility. When he sings while playing the keyboard or synthesizer, Wonpil’s distinctive melancholic yet warm voice is layered onto the song, making that emotion feel amplified. His sincere vocals and ability to convey lyrics, which seem to comfort the listener's heart, are truly tremendous charm points; watching him fully immerse himself in the music on stage naturally draws me deeply in.
