Pages 4 and 5 killed it for me.
No, I don't mean that in a good way.
This shithead just wakes up looking like a generic isekai protagonist with overly tight trousers, narrates the whole thing in douchebag terms, comments on his new body's genitals, then makes the unforgivable error of referring to glasses as "plain".
Dropped in the first 5 pages. That is a new record.
