Female Supporting Counterattack

When Jun Feifei woke up, she found that she had traveled through time and entered a novel about Mary Sue. It's a pity that she is not a heroine who is loved by everyone, with flowers blooming and cars everywhere, but a supporting female character who does all kinds of evil and meets a tragic end. Once she traveled through time and became a female supporting character, from then on the heroine was just a passerby. Watch how the funny heroine conquers the cold brother who is not a biological brother and sister*^ω^* This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
