Seita, a protagonist who loves isekai light novels, is suddenly transported to another world (?) by a certain turn of events!?

At first, the carefree Seita is delighted, but...

This is my first isekai story! I believe it follows a classic (traditional) formula (?), so I'd be grateful if you'd give it a read!

(Updates will be irregular, but I'm writing it as a "short-long story" (I know, it sounds contradictory), so I appreciate your support!)
