One viewer expressed his or her concern about the awkwardness upon first meeting somebody to which Sunny responded, "To tell the truth, I was severely closed to strangers, as well, so up to my debut, I did not know how to sociably talk to somebody I met for the first time.

After debuting, seeing what my work called for, I realized that if I acted like it was no big deal around somebody I met for the first time, it made that person feel comfortable and the broadcasting went well. �I purposely, forcefully changed my personality.

Firstly, if you want to leave a good first impression during your first meeting, you must greet them brightly with a smiling face and it is important to introduce yourself. �In addition, when talking with each other, you must look for common interests. �If you converse like this, the awkwardness in a first meeting will go away."
