When asked to share a thought about IOI, Jinyoung said, "I feel like they are another me because I went through the same thing as them. I had the dreams they had and had the same thoughts. It amazes me to see them succeed after seeing what they went through. I can relate to them, and even though I'm lacking, I want to be able to give something to them."

As for the track "Hold On", Jinyoung said, "I was asked to write a song when I was filming for the drama. I was happy and also thought I was lucky. I don't think I should find it tiring to be working a lot. I think it's my job to complete the tasks given to me well. So I said I'll make time, and I'll love to do it." 

Isn't Jinyoung such a supportive sunbae to IOI?
