Reviewde @ch39/season 1 end
It's your normal Returnee story though they throw in a couple things that might surprise you like a Summoned Hero who's a secondary/side character, or monsters coming through gates up north for some random reason.
MC uses typical peggy sue means to take advantage of resources/events. Unfortunately a couple of these feel too random...What are tha chances a pandemic just happens to occur two months after her time travel? stuff like that.
But the main character IS good. Male lead is ok. Antagonists are...so far underwhelming. Summon Hero might be decent, will have to wait and see.
So far, I'd only recommend if you like the genre. It's good, not exceptional. But we're only one season in. And I did have a fun time.
