They’re 6 years apart
- She was 20 and he was 14 when they met
- In this flashback’s timeline (when they’re making out, etc), he’s 19 so she’s 25
- Since this is 7 years in the past, the story’s current timeline should be in 3 more years (once he’s a proper king) where I’m guessing she’ll be 28 and he’ll be 22

Well, it makes sense for the time period the story is set in. If it was a story set in modern days, I’d rather she be 20 before they got anywhere to make it palatable, but the age gap makes sense for this setting.
I personally think the author fked up regardless, though. We know she’s 24 inside, so why not make everyone know that so it’s less weird? And why not make her grow back to her real age after she got poisoned and he healed her, since he was the one who reverted her backward? Two missed opportunities right there. I’m annoyed at the potential of the story just taking a nosedive because of that.
What is their age gap?
