Fat Cat and Boyfriend did a collaboration piece.

Fat Cat sang 'Is being pretty everything' on January 28th broadcast of MBC 'Show! Music Core'. On this day Fat Cat was rejected by Young Min and Kwang Min during the kiss performance.

Fat Cat was being cute by air-kissing Young Min and Kwang Min but the twins looked unhappy. The audience cheered on the twins at their attempt at a new performance.
