Our freakin theory was truuuue, there was an Allen before the one we know and he offered his body (thank god I have a good memory to remember sh*t that happened centuries ago (〜 ̄△ ̄)〜)

Right so, it was 20-30 chapters ago when Nea woke up instead of Allen he talked with Timcanpy to know what's going on and he wondered why Allen was young again and why he didn't remember him. Since then we had 2 or 3 little flash back from Nea about a man who is supposedly Allen in one of wich he tells Nea to give him his memories, promising he's gonna protect them. That's why Cross was searching for someone named Allen and was surprised to have found a kid. The name Allen was the only clue he had in finding Nea's reincarnation.
So yeah . . . we call him Pasta for Past-Allen and also foodpun.
Anyway seems like Pasta was a close friend of Nea. Not gonna lie I didn't think Allen was gonna learn he was alive 35 years ago this early. Nobody seems to know that exept for Nea and Apocryphos. Like I don't think Cross, Road and Wisely knew, whitch is crazy.

well, now I can know all your opinions about this.
MY THEORY.....
I think now I can come up with a theory. The cat said that a talented administrator like him, in the past, tried to become human, and that's the reason why they can't have human form anymore. Also, MC has green eyes and that would explain why he didn't have "emotions". Maybe he somehow escaped and he is now trapped or has to live like this. Maybe, he was the one in charge of the villain Qin Xian that they show in flashbacks. So they are connected and Qin Xian is remembering little by little. Or something like that. Aaaaah I missed this. (≧∀≦)
It can't be too happy. I'm sure she means problems or something bad is going to happen. I have trust issues
