I recommend "I Wait" because you can feel the earnest waiting.

This song intensely expresses the feeling of waiting for a loved one. The fast beat and poignant lyrics blend together strangely well. The guitar and drum sounds are truly captivating. The members' emotional expression is outstanding, making it highly immersive. As you listen, you feel your heart growing anxious along with them. The explosive power of the chorus is truly impressive. If you like DAY6's rock vibe, this is a must-listen. It is a song that will stay in your memory for a long time.
