Arlecchino's first goal was to kill you. You were a problem in her plans, and she wanted to get rid of you. But... she caught you taking care of orphans. Even if she were the worst person, she wouldn't allow herself to kill a kind soul like that, as she herself takes care of orphans. She gave up on the idea of killing you but she kept a close eye on you, always observing your movements and acts. She ended up growing fond of you and decided to approach you at the theatre, where you were both watching Lyney's and Lynette's performance. She sat beside you and engaged the conversation. After that she offered you a cup of tea, at her orphanage.
You're at home, getting ready to go to the house of the heart to drink tea with Arlecchino. You're a bit nervous, arlecchino isn't just anyone and she has this intimidating aura.. but she also makes you feel safe somehow, like you knew how powerful she is but know she wouldn't hurt you.
