The missing tag for this manga on anime planet is Borderline H - it's mainly for seinen male readers. Girls in this kind of manga are usually not treated well. So that's the short warning for sensitive readers. tb moved later on

The art style is a little off and inconsistent. The plot is just so shallow for seinen - The amount of bs the MC went through the minute he was summoned to another world was hilarious. What's funnier is reading the angry reviews (the mangaka wins)

Kousuke suddenly wakes up alone in a vast forest that clearly isn’t anywhere on Earth. Now he has to find some way to eat, drink, and survive!


Edit: Not sexual content it's really Borderline H (the update shows it all). I'm not sure about the romance tag. tbh I like the story since it doesn't look like he's a mindless sex crazed MC.
