I feel like there is a lot of potential wasted. And one of the reasons is rushing again. At least it would be if this was an original anime. It could have been better if he would have waited before telling side characters who he is, because he does not know what has changed since last time. Or if he told the king who he is. Both could have waited till the 2nd episode, while 1st one would be him catching up to things and remembering the past.
I saw this anime being mentioned somewhere and it struck me, that the title actually kind of lies about the synopsis. It was not that the guy was summoned tot he same "other world" twice, but that he was born in this "other world", then isekaid to "modern world", and then got isekaid again, but now back to his own "other world". He was reincarnated twice, since the 2nd time seemed to be a summoning.
