I like "Yeppeotseo" because of its wistful and sentimental atmosphere.

The lyrics that remind me of a past love are impressive.
The emotions in the vocals are conveyed naturally.
It starts calmly, but becomes more immersive as it progresses toward the end.
It feels like the meaning of the lyrics comes to me in a new way every time I listen to them.
It is a song that people who have experienced a breakup can relate to even more.
It is a DAY6 masterpiece that will be remembered for a long time.
