What the heck is this? Pls enlightened me why the heck the FL need to have an affair just so his cheating fiance would annul the engagement??? Didn't he said he will annul it when he said he's dating the ori FL? And now the cheating bastard won't annul it cause she have someone too?? Wouldn't this make she look bad too for having an affair????WHAT KIND OF DUMB PLOT IS THIS??? Does this get better??? The art is okay but man, the plot is kinda stupid so far
