What? A villainess actually acting villainous? With a family that's actually involved and keeping track of things?
I quite like this one. It has a good reason for why someone would want to force a break-up and set something else up in a subtle way, and the baggage that can come with some relationships. It also has a good-feeling comeuppance, and maintains an amusing tone throughout.
My ratings on the series, from best to worst:
1-2, 2-3, 2-4, 6-4, 4-5, 5-2, 6-1, 2-2, 4-1, 5-5, 2-1, 1-4, 3-2, 4-4, 4-3, 4-2, 3-1, 6-3, 5-1, 4-6, 2-6, 5-4, 1-5, 3-3, 3-4, 1-3, 2-5, 3-5, 5-3, 6-2, 1-1
