What should I do

What should I do a song by Shin Yumi on BeMusic

Like that smiling face letting me go by KIM SO YEON, Various Artists, KIM KI TAE,
What should I do by KIM SO YEON, Various Artists, KIM KI TAE,
Those Days by KIM SO YEON, Various Artists, KIM KI TAE,
Like The First Feeling by KIM SO YEON, Various Artists, KIM KI TAE,
When lilac is falling by KIM SO YEON, Various Artists, KIM KI TAE,
