@Jack . 10 years ago. Sae was 15 when she lost her parents.
She's 25 now. We don't know how old Sohaku is. But he was a military doctor when the fire happened. He's definitely older than her. But they're both consenting parties.
We don't know how old her scumbag ex husband was when he married Sae but we do know that Sae was 16 or 17 when she married him.
