He's bad but good !

"Your father paid me.I didn't want to accept the money but he insisted."
"Why did he gave them to you?"
"Just because I told him I don't have any money."
"Such an obvious lie.You could've asked me to give you money.Tell me the truth."
"It's going to hurt you too much.I know because I was terrified when I found out."
"Stop finding excuses and tell me everything."
"Alright.When I arrived at mom I found your father there.I decided to not enter the room and wait next to the half opened door.But unfortunately I heard their conversation." takes a break.
"Go on."
"My brother is...."
"Sick?"
"Not even close...my brother"sighs"is also your brother."
"What?Why?How is that even this possible?"shocked.I'm shocked.Is she serious?
"They had slept togheter she was pregnant and they decided to make us marry so he has a reason to give her money."
"This is so messed up."My mind is confused.
"He gave me money to shut up.Didn't want to accept but you know how I used the money."
"I don't know what to say."
"Don't say anything.Anymore.Never.Your mom can't find out."
"Does he...love your mom?"
"Why ask that?"
"I need to know."
"It was just a ONS for both.No feelings."
"You asked them?"
"Of course.I was as shocked as you are."
"You can't tell your mom.You have to forget.We have to forget."I come to my senses and think logically."If mom finds out she'll divorce him.They will want to get married.And they can't.After the old man dies he will make me divorce you and we will become siblings."
"No.It can't be.We are not divorcing."
"I gave him my word.He will do everything to split us.Mom can't find out."
"Don't worry.That's why he paid me.To keep my mouth shut."
"Until the old man dies and we will divorce.Nothing keeps him next to mom.He has his own bussines which isn't related to mom and he will not lose to much money after the divorce."
