HERE'S the actual ending for all of y'all that are unsatisfied
Rina, after months of working as a single mom, struggled with paying the debt she had to pay for her in laws. When she couldn't pay, she would take money out of her kid's education funds.
When her kids saw how much trashy she was she was struggling, they decided to leave that hellhole.
They ran into a businessman who had many salons in the area( the guy that that douchebag impersonated).
The kind businessman adopted them after seeing the situation they were in.
Since Rina didn't pay off her debts she was sent to court where she brought out the truth about her abusive relationship. Trashy ex husband got put in jail for his actions and Rina's debt was halved.
She still had to work off her debt by scrubbing dirty public areas.
As for Junpei, his mother actually got sick. As there wasn't enough money to pay the hospital bills, Azu was overburdened with work.
His mom got better, Azu didn't.
She signed the divorce papers after realising this relationship was too much to handle.
So Junpei ended sad and alone.
Note: this is totally the true ending of the story
