JYJ's Yoochun posted a new tweet that's become the center of hot attention. A shoutout to his younger brother, Yoohwan, seems innocuous enough, but netizens believe that it hints at greater things.   On December 25th, he wrote, "Yoohwan, whom I love!!!! ^^ Do well from now on." The picture uploaded with the tweet shows off his brother's masculine charisma, which stands in contrast to Yoochun's characteristic 'flowerboy image'. The 'Do well from now on' line has led to speculations that Yoohwan could be debuting in the music industry. Netizens commented, "This is the first time that I am seeing a clear face of him," and "Is he debuting in the industry soon?" Source: TV Daily via Nate
