On January 5, ASTRO went live on Naver V app with the title 'ASTRO's Rooftop Live'. During the airing, the members congratulated Rocky on turning 20-years-old this year, and each named the things they wanted to do when they turn 20. 

Cha Eun Woo first shared that he achieved his goal to obtain a driver's license. Maknae Sanha commented, "I'm going to get mine right after my birthday this year."

Members then asked the oldest member MJ, "When do you old?" MJ replied, "I don't feel old yet." On the other hand, Moonbin revealed, "There times when I feel old. We were the first boy group of Fantagio but now, it's not just us. There are many trainees. Whenever I see them, it reminds me of my past. I came to think that I need to work harder and become a help to them."
