After re- reading the whole thing again i start to question does the thought process of kl...

The original Mc and ml will never meet again the second time line was for the Mc to live it and the third is for the ml but theses two souls that suffered in the first time line shall never ever reunite

Yeah ik. But the stuffs that kloff thoight about aeroc in second timeline, about how he looks adorable, beautiful, that when aeroc smiles he hates it because then he can’t scold or shout at him. Does the first timeline kloff also think like this about first timeline aeroc. The FT1 is heavily focused on Aeroc’s pov that we hardly get to see Kloff pov or inner thoughts about his feelings for aeroc, but in the second timeline we see it all from kloff’s perspective. Since this is a reincarnation and not much changed except for the fact that aeroc remembers everything, the evidences of kloff thoughts about aeroc, could it also mean that TL1 kloff before witnessing Rapiel’s death and started hating aeroc also thought of aeroc as adorable, beautiful, and everything the TL2 kloff is thinking.

I think, yes In 1st tml kloof trough the same things about Aeroc as 2nd GML, but he didn't make move nor admited his feelings because both of them were alphas in 1st tml and Aerocs action just made Kloff distance himself more since he hated his aristocrats attitude.
But in 2nd tml, same happened but something in Aero changes (he had experience and maturity that he didn't in 1st or he just showed less arrogance) that did a butterfly effect on kloffs trough process... And kloff has no other reason to deny his feelings for aeroc

Or I just assume so...

And also Kloff didn't make move BC his dream was to live a quiet life with a nice omega even if he didn't love that omega completely and Raphael's (or whatever his name was) fitted this description to well so he didn't want to love this opportunity over Aeroc... So he denied even more his feelings which also sparked some kind of hatred for Aeroc other than Aeroc being aristocrate.

Or something like that

Also to me it was obvious that Kloff repeatedly used Rapiel to stir up Aeroc’s jealousy.
So kloff actually was very attracted to Aeroc, he even dated a omega that looked like him...
