Actually prologue a small intro to a play/literary works. Its is something opposite to epilogue, which is what Fusheng like to do in his Fusheng Diary - an ending summary.
Though most of us are not unfamiliar of MDWAV series. There might be some who watch it for the first time. Esp with the speculated change in main casts, one might be lost if some intro is not done.
I had this funny idea: why not we gather our minds to come up with prologues or the main story. Then compare it when the real show come out. See which story plot is more adhering to what Chan13's thinking? No need to be a long one (for prologue), a gist will do (for Main Story).
Wonder if the thread moderator will support this....
