During their first night sharing a room, Yuzu had her first kiss stolen by her step sister. Since then she can't get Mei off her mind, while Mei herself goes on as if nothing happened. Meanwhile, Mei's Grandfather, the chairman of Aihara Academy, takes Mei back to his mansion. Unable to forget the sad expression on Mei's face when they kissed, Yuzu heads to the mansion to confirm Mei's true feelings, but...?!
but why's she suddenly 
acting like a stranger?
aber warum tut sie plötzlich so,
als würden wir uns nicht kennen?
pero ¿por qué me trata
como a una extraña?
pero ¿por qué me trata
como a una desconocida?
mais bon,
de là à faire genre on se connaît pas !
Ma perché comportarsi 
come fossimo estranee?
Mas por que ela está agindo
como se não me conhecesse?
но зачем вести себя так,
будто я тебе чужая?
