jisung said he was drunk while drinking in leeknow's room and they were listening to ‘leo’ by yuuri. jisung suddenly cried and gave leeknow compliments "hyung, you have such a nice voice. you're taking vocal lessons and improving so much. you're getting better and you'll keep getting better. hyung can do anything. i really like you, hyung. your voice has so much vibe" jisung was saying the same thing for 2 whole hours and leeknow just listened to him and he could feel that jisung was being genuine!
