A rookie K-Pop idol made a cute mistake at his first ever fan sign, causing laughter.

On April 5, Cube Entertainment's new rookie boy group NOWADAYS hosted their first in-person fan sign event with fans. 

One fan who attended the event later realized that maknae Siyun wrote, "TO. Siyun," instead of the fan's name, most likely because he was so nervous. 

Well, the idol made up for his cute mistake by charming fans at the event with his unending aegyo.
