On June 28th, 2AM's Jo Kwon reminded us of his close friendship with 2PM's Nichkhun. Jo Kwon tweeted the picture below saying, "After finally finishing my schedule I came back to the dorm feeling really tired~ and on my bed there was Nichkhun hyung's message~ He must have dropped by our dorm, I feel like my strength is back ?? Thank you hyung-ah~ ^^*thank u Khun." On the note, Nichkhun�had written, "Kwon-ah~ I love you~" and had signed his name underneath. It's heartwarming to see how close these two are!
