In my opinion this is somewhat similar,
The Last Adventurer (Going back to the past but like the MC here, everywhere he goes is trouble lol)
The Knight King Who Returned with a God (I rec this the most and you'll know once you read it)
Sorry, I'd Like to Save the World, But I Have a Deadline to Meet (OP MC but gotta lay low since he 'retired', they are both called a hero)

Can I get some recs for Manwha like this
