Once upon a time, there was a little boy. He loved his mom more than anything. Every day when his mom came home from work, he would run to her and give her a big hug. He would also pick little flowers from the garden and present them to his mom. He said those flowers were as beautiful as her.
Well, it could be that the son's friend has some sort of secret about the mom that he's using to blackmail her. Maybe she made a mistake in the past that she doesn't want her son or others to know about.
The main characters are the mom and son in the 'Reluctant Jzp Mom and Son Story'. The 'reluctant' part might suggest that the mom has some sort of complex or conflicted feelings towards her son. But we can't say more about who they are specifically without additional details.
If the mom is reluctant but still doing the blackmail, it's likely that she's in some sort of difficult situation herself. Maybe she's in debt or has some secrets she doesn't want exposed. However, blackmailing her son's friend is completely wrong. The friend might choose to confront the mom and try to reason with her, or he could cut off all ties with the family which would be sad for the son.
It's not really a matter of fault. The mom was just reluctant and underestimated her son's capabilities. But it's not her fault as she might not have been fully aware of what her son could do. And the son's friend was just making a bet based on his belief in the son. So no one is really at fault here.
Maybe the son's friend made a bet with the mom about something like the son's academic performance. If the son achieved a certain goal, the mom would lose the bet. For example, the friend bet that the son would get all A's in a semester, and the mom didn't think it was possible. But in the end, the son did it, and the mom had to accept the loss of the bet.
One way could be for the mom to confront the son's friend directly and tell him that she won't be blackmailed. She could threaten to go to the authorities if he doesn't stop.
