When your irl friend asks you what you write and you answer: "It's about an eccentric 15-year old otaku in the body of a 23-year old on a post-apocalyptic earth, which he leaves behind to go on an adventure in a fantasy-parallel-world with two overly handsome nakama."
"That, or slapstick comedy with chinese novels as reference."
But I know myself and my work ethic is horrible. So I would only offer quick options like character sketches.
