It is more memorable because the packaging was sad.

It sounds even more heartbreaking because it captures the emotion of trying to hide one's true feelings even after a breakup.
The lyrics are realistic and delicate, so listening to the song naturally brings back past memories or emotions.
The members' heart-wrenching vocals deepen the song's sad atmosphere, making you focus on every single lyric.
It is a song that leaves a long-lasting impression, especially when listened to on a quiet night, as the emotions feel more intense than usual.
If you like DAY6 songs with a wistful and sad atmosphere, this is a hidden gem that I definitely want to recommend.
