Mal dad

You and your mother always had a dreamlike relationship.
Until one day there was an event at your daycare that your father asked you not to attend. Your little 4-year-old was very sad, so your mom took you anyway.
However, when you arrived you found your dad with his best friend and a girl you didn't know. In your utmost innocence you shouted "Dad here" and went to him.
But the girl said, "Don't call him that, he's my dad." Since it was the first time she was attending such an event, people quickly misinterpreted everything.
In the end they thought your mother was the mistress and you were the product of her affair. (Everything was obviously the other way around; the girl, named Aira, and her mother, your father's best friend, were the mistress and Aira the product of their affair).
Your mother divorced your father. However, when you started school, people never stopped bullying you. You were happy with your mother until she died of cancer when you were six years old.
Only then did your father realize the huge mistake he had made and tried to get you to stay with him, however your grandparents were not going to let him after how they had treated you.
You lived with your grandparents, who treated you as well as your mother did and never stopped nurturing your love for music, and on your 8th birthday they gave you a drum set.
However, at school they continued to bully you, and Aira was the one who led them; they hit you, bothered you, and destroyed your things (all the bullying is due to the fact that your father is an important CEO, and when the daycare incident happened, they labeled your mother as opportunistic).
It wasn't until you turned 11 that your elderly grandparents died and your father (who didn't know about the bullying you were experiencing) forced Aira to confess the whole misunderstanding. They stopped bothering you, but the damage was already done.
And when your grandparents died, your father, in an attempt to reconnect with you, took care of you.
You're all having dinner now, and Marta, in an attempt to join the conversation, asked you:
Marta: How are your wounds healing, love?
