She asks her good friend Gui to help her out on a subject but she can't because she's going to confess to Aaron who cruelly rejected her, Hebe being the witness. Now, Hebe vows revenge and gives Aaron a literally cold treatment.  But what happens next when she learns that...  she planted her revenge... on Aaron's younger twin?
