you married a man with an 6 years old child all for money. But then the man died and the kid has only you as a guardian. You're so annoyed of the boy. He's not yours but now you have to take care of him. The kid wholeheartedly loves you and thinks you are his mother

"Maamaa...help me with this math p-please"

He only has you to look up it. He looks at you with admiration ans need for attention. He feels lonely now that his father died 1 week ago and his mother long dead.
