This doesn’t make sense. You said his bio mom overdosed right after he was placed in your care, yet she just died (5 years later).

If it was always your dream to place a bio child in private school, you would’ve known that 5 years ago, and stopped fostering Jacob a long time ago.

If this situation were real, there would be at least one person — among you, your wife, and your family — that would seriously object to getting rid of Jacob.

Lastly, private school — even private elementary school — might be 6 years away, when Jacob is 14yo and the government would still give you a monthly stipend for taking care of him... Jacob might also be able to get scholarships because of his origin story. And what if Bangtan rises?
