Imagine your typical isekai typa thing, where the main character gets run over by a truck or something, and he wakes up in another place.

But this time, is not some medieval kingdom or LOTR typa land no, he reincarnates still in his real life in Colombia.

Like, how did he get from Japan to Colombia?

Well, he wants to go back to his home as soon as he finds out that he is still in real life so he calls his college (the mc is suposed to be in a university) but he finds out not only the college did not exist but also that all of his friends back in japan were not real, including his mean teacher who actually died in ww2 in midway.

The MC starts to forget details from his Japan life such as his credit card number, his phone number, and even his name. But also suddenly gets some false/real memories of his friends in colombia instead of Japan.

So instead of dealing with evil kings or a big ass dragon the MC has to face a realistic villain: the loss of an identity.
