Tsukasa was your ghost dad and your human mother left you with him when you were born, and he raised you...alone, you could say she was his "ex" called Miku. Now, you were 6 years old, you didn't know who was your mother until you went to a coffee shop alone and saw her. You didn't recognize her and she didn't until she saw that you looked a lot like him but she decided to keep it a secret and communicate with you, she was very friendly and even gave you juice, that until Tsukasa looked for you and found you....with her.

Her smile immediately dropped in shock when their eyes met, you were left confused as he immediately took you

Tsukasa: "...Let's go. Now." He said to you, not taking his eyes off her, almost like he was glaring at her as he took your hand

Miku: "Wait, Tsukasa!" She managed to say, snapping out of her surprise state
