On March 30, Oh My Girl members Seunghee, Yubin, Mimi, Jiho, and Hyojung appeared as guests on the SBS power FM radio program, 'Cultwo Show'.

On this day, member Yubin introduced herself and mentioned to listeners that she has decided to change her stage name. Originally, Yubin debuted with the stage name Binnie. 

When asked why she decided to change her stage name, Yubin stated, "The biggest reason is that I like to be called by my given name a lot." 

DJ Kim Tae Kyun then remarked, "It should have just been Yubin from the beginning. Binnie is also just a friendly way of referring to Yubin, isn't it?" 

Yubin then responded, "But when I first debut, the company set it as a rule that 'I must live as Binnie'. I asked the company to consider changing it for many years, actually. After considering it for 3 years, my request was finally accepted."

Finally, Yubin added on, "I feel energized when people call me by my real name."
