Harmino: Wrecking Miss Promiscuous (Les Tendres Series #5)

Mnemosyne Zcimin Crosette was born with four other siblings. They're all girls... And identical quintuplets. From America where they were born by their mother who abandoned them, they were raised by a Filipina stranger, their Aunt Claire. Until their aunt passed away, the quintuplets had to separate and move to the house of their aunt's close relatives.

She felt that she had caught all the bad luck in the whole world when she found out that she was going to live in the house with Nirca Elaine Harmino, the girl known in the university for being a promiscuous lesbian who only likes to wreck gorgeous girls inside or outside the campus.
