On July 8, ASTRO appeared as a guest on KBS 2TVs Immortal Song and was asked which idol group they liked the most.
Cha Eun Woo replied, When I go on Youtube, BTOB always appears in my list of recommended videos.
Following this, he was asked who he looks up to the most in BTOB, and Yook Sungjae, who was a part of the cast that day as well, started to drink water and showed signs of nervousness.
Seeing this, Cha Eun Woo responded, Its Yook Sungjae, and the delighted BTOB member reciprocated the love by giving Cha Eun Woo a heartfelt hug.
