Spoiler alright

- both ML and MC SHOULD have regressed, but ML was stuck in his created space because his 20 y/o self (2nd timeline) can't handle his mature self's (1st timeline) powers
- only MC successfully regressed and he started anew with the 2nd timeline

2nd timeline ML:

- the MC and ML worked out their differences in culture (espers were raised to kinda think that r*pe guiding is alright by their government for guiding efficiency), meanwhile MC was raised in civilian culture where they were blocked from knowing the true guide/esper system (which basically meant espers/guides we're raised kinda inhumanely) so the MC tried to correct that and a lot more of their wrong culture
- while battling against monsters, opposing officials attempted to kill the ML, but MC block it and ended up dying
- after MC died for the 2nd time, he met the 1st timeline ML and found out his forgotten memory, that they (1st ML and MC) should have regressed and corrected all their regrets
- I'll leave what happened to them at this point hehe

----> fast forward to ending

- comes their healing from each other and from the government treatment, this was especially apparent in side stories because ML was separated from his family at infancy, so MC did something to make up for ML's lost childhood
