I wonder how many "green tea bitch" characters turn out that way because the author doesn't know how to handle a genuinely "nice and sincere" character (that's not a lead) being justifiably, or even irrationally, jealous/insulted/angry/defensive/whatever. Yeah, some of them are obviously putting on a facade, and the easiest way to change a "nice" character into an enemy is "hey, they were faking it!" but even nice, well-behaved people have to draw the line somewhere or they are actually just doormats. Just wondering as I see the author retconning this personality change, why all the other possible love interests have to be evil, when it is merely sufficient that they aren't Yuan Chu.
Eh.
