Jung Chae Yeon of IOI and DIA sat in the car of reporter Lee Jin Ho for his 'Sing Car' show, which airs through Afreeca TV, on July 19!

On this day, she talked about many different things.  Lee Jin Ho asked, "How are promotions in DIA after getting popular through IOI?" and she replied, "I was half-scared and half-excited, but I just did everything diligently with gratitude.  I engaged myself with the thoughts that I should have fun and do my best in everything.  I grew more grateful while promoting.  I thought I had to work even harder."

During their talk, she also exclaimed, "Today's Tuesday!  Today is IOI Kim So Hye's birthday.  Happy birthday, Kim So Hye!  I had really written this on my calendar," and showed proof on her cell phone.

When he next asked, "Which celebrities have you gotten closer to while promoting as a celebrity?" she replied, "I am so close to all of the IOI members.  People could misunderstand us because we are all under different agencies, but when we're having a hard time, we text our concerns to one another and give advice.  We talk on the phone, too, and when my schedule is clear, I go to play at their dorm once in a while."

Good to hear they're all still close!
