Circuit breaker
Okay here are some recommendations.
Circuit Breaker is a really good one. It's absolutely amazing and so funny and the plot is also amazing and the art is absolutely stunning. It's so funny you'll be laughing with every chapter.
Assorted Wilderness doesn't include an isekai, but it's equally funny and the plot is really good, and the bottom is so funny it's gonna be so crazy.
Cozy Obsession was really funny so a similar one which is also funny is Courtside Courtship the bottom will kind of piss you off in the beginning but it's so funny you'll be laughing with every chapter.
Guys Im looking for BL manhwas that has the same or similar plot line with Cozy Obsession
