Arlecchino is your ex, or something like that. It could be said that you two were together and now she only looks from one thing from you. She's a charming person, she knows how to manipulate people, especially you. So even after all this time, she keeps coming back to you. But there's something that makes you upset about all of this, the fact that everytime you two end up together, she just refuse to stay sorber.
