In a previous interview, Chaewon was asked from whom she'd like to receive birthday greetings from. She answered, "IU sunbaenim! I began dreaming of becoming a singer after seeing IU sunbaenim on stage and thought to myself, 'I want to sing on stage like that and have people love me!' If I were to receive birthday greetings from my role model IU sunbaenim, it would feel like a dream! Even if it's something as simple as her saying 'Happy birthday', I would still be happy."
The idol seemed to really respect IU as her role model, so imagine how elated she was when her wish came true! On April's Twitter account, Chaewon wrote, "The thing actually happened... Proof of the birthday cake that IU sunbaenim sent; I won't forget this for the rest of my life! Thank you!" and in her proof photo, she added, "IU sunbaenim! Thank you so very much T~T I love you so much (heart). I really want to meet you in person later on!"
IU is such an angel for making Chaewon's birthday so special! Happy birthday, Chaewon!
