I think you confused kana for saito ichigo - ai's director and miyako's (probably ex)husband.
kana hasn't shown any kind of ptsd.
this is kana's interview: https://guya.moe/read/manga/Oshi-no-Ko/6/1/ . 'a-kun' is probably aqua she probably still hangs around the twins.

I disagree, aqua's thought process was pretty calculating, but he did tell kana the truth (to help his sister) , didn't bully kana nor is he trying to screw over her career.
Hopefully Kana doesn't regret becoming an idol.
It doesn't seem like she wants to be anything but an actress and being an idol carries some "baggage" that's hard to get rid of.
