“King of Delusions” Manhwa Engsub

King of Delusions is a hilarious and steamy adult isekai fantasy about Soujou Hanata, a reclusive part-timer whose only escape is a lewd PC game called King of Delusions. After a long day at the convenience store, he discovers a mysterious “secret mode” in the game—and wakes up inside its world, where he’s suddenly the overpowered ruler of a realm filled with magic, monsters… and tempting maidens. In this fantasy, his wildest delusions may just come true.
