I don't think so, cause if we base it on the presented flashbacks, Hanna (his daughter) is older than Thaddeus (young thaddeus). And Thaddeus is on his early 20s now while Yuna is 19 (i think?). (Just sharing!)
I think she might be peters granddaughter instead, so Hannahs daughter
The present is in 2021 so yuna which is I think 17 (shes in highschool so) mustve been born in 2004
In the flashbacks which if I remember well is from 1989, hannah was around 5years old, maybe older but at least 5
If she had her daughter at 20 then it does match, and yuna grew up in the orphanage so im guessing something happened with hannah
Yeah i have the same thought too.
After all those chapters i still.cant.shake.the thought that Yuna is Peter's "daughter"...dont ask.why....
