I like "I'll Leave It Behind" because it leaves a deep lingering impression.

I'll leave it behind "..." is a ballad that calmly expresses the memories that remain even after a breakup. The gentle piano and band sound blend beautifully. The members' heartfelt vocals convey the emotions even more deeply. It is a song that feels even more sentimental when listened to at night. It is a hidden gem by DAY6 that leaves a lasting impression.
