Being a blind person is not a hindrance to be a musician for Lee Jihoon. He likes music, and he creates them from his heart, not his eyes. He never thought of taking back his sight, until a man named Kim Mingyu tried to interfere his life. Causing him to be in the verge of breakdown, and desired to see the man in his hold.

Jihoon wants to kill himself. Seungcheol wants to revive himself. Life in a mess, and with the help of each other, they tried to recover from the darkness in their whole existence.

Nayeon had to feel the feeling she wanted to avoid for her childhood friend since birth. Love is painful. Even more when Seungcheol rejected her undirect confession.

Momo is Hoshi’s biggest fan that comes from Japan only to learn dancing from him. Though the effect seems more effective to Hoshi for having thoughts that Momo is the girl who is perfect for him.
