Did I miss something? Can someone explain why it's the third timeline? I thought it's just two

Well, mainly bc Aster just straight up says she already had "two whole lives", and that she married her husband twice. So that means she's at least on her 3rd life.
Also, note that in the beginning she asked her mom what she'd do if she could go back in time, and practically begged her mom not to remarry Harold, and made the mom *promise* not to do so. That's likely because mom already fucked up a regression by remarrying Harold, putting them in that mess again. So Aster was like "bruh, forget about me. Go live. Seriously. Promise me you'll marry someone else. Everything will be fineee". But her mom almost fucked it up again, but ended up with Schderl. So that also means Aster is on her 3rd life.

Eiser needs to teach a lot of things to his wife princess, aside from the hot stuffs, he needs to teach her not to trust that dirty Dia.
I would be disappointed if Eiser won't be on time to interrupt whatever Dia is planning. Serena is smart but she can be naive about some stuffs.
As for people who cannot wrap up their minds how Serena can be clueless at some things. remembe that her family who was supposed to teach her upon reaching adulthood died, and she wasn't in good terms with her grandma at that time as well. Also it isn't like they have access to info thru internet like most teens nowadays who knows a lot about adult stuff even without anyone teaching them.

I'm guessing that the "real" Ayla isn't really "bad" but she's deliberately acting such to protect herself or someone.
And there's probably no other Ayla but she just indeed forgotten about it and remembers her other life instead.
So she chasing Frede before may have other reasons than his face. anyhow all the evidences points at glasses guy and he is probably involved but there's a possibility its someone else unexpected like her mom
