OK, I will have a go - hopefully someone will correct me if I'm wrong!
활동을안하세요? = Aren't you doing any activities?
좋아요 입빠이 눌릴 준비가 되어잇는디 is difficult -
I think 좋아요 xxx 준비가 되어있는다 means "good, all ready to xxxx"
입빠이 seems to be a japanese word いっぱい meaning 'full', so maybe it means "good, totally ready to xxxx"
I'm confused by 눌릴 though which means something like "press".
이해하지 못했어요 = I couldn't understand
