Miss A member Fei listed having a Korean boyfriend as the #1 tip to learn Korean quickly.

On the July 28 live Naver broadcast of "JYP Nation One mic talk," Fei was asked for tips in learning Korean quickly. Fei responded, "Korean improves quickly when you have a Korean boyfriend."

2AM's Changmin responded: "Does this mean you have a boyfriend? Why are you digging your own grave?" Fei answered back: "No, I don't. If you don't have a boyfriend, you can make lots of Korean friends."

In this broadcast, JYP Entertainment artists like 2PM, 2AM, Miss A, GOT7, Baek Ye Rin, Baek Ah Yeon, and Park Ji Min were featured. JYP Entertainment artists will hold a joint concert on August 9-10 at Seoul's Jamsil Stadium.
