J.Y. Park said, "I don't make songs for GOT7 and TWICE. I wrote songs for g.o.d because I know them well, but with the other friends [GOT7 and TWICE], we are not in relationships where we can talk about life." 

He continued, "To be honest, I miss the g.o.d days. The first song I wrote was g.o.d's "Dear Mother". When I heard Park Joon Hyung's story it broke my heart. If I get to create another girl group then I will want to find out more about what's on their mind."
