hmmm...there were two break ups wor...the second one was written by Kitten =)...I'm not sure if you are that far ahead, but the first break up is because during one of ah Fei's investigations they found a skeleton and ah Fei thought it was Chin Chin's (because she was wearing the bracelet) so he went crazy lol...then ah Quin realized that he cared about Chin Chin more than herself so she broke up with him, but then it turned out that the skeleton was not Chin Chin and ah Fei tried everything to get ah Quin back and they eventually got back together...and that's when the real Chin Chin comes back and the second break up happens (read Kitten's)...
