Hyunseung believes he lives an average life, a normal and acceptable one to the society. By following the routines and rules and not sticking up into anyone’s business; his life is rather very normal. Just until three boys decided to make his so called normal life into an adrenaline and rush-filled roller coaster; making him very confused as to what did he do to deserve such treatment from them.  Apparently all of them love him but Hyunseung has only one heart. Who will he choose to return the favor with?
