It is Jimin's solo song, the second main character of the short film, produced by producer and keyboardist Doc Skim and singer-songwriter Sumin.
It contains the situation of falling deeper and deeper into the mire as he lies and does bad things for the first time, and the agony of a boy struggling to get out of it.
The Spanish guitar sound, impactful rhythm track, and cool and melodic vocals are impressive.
Jimin's voice, which is powerful and soft at the same time, added to the perfection of the song.
