Can somebody give me recommendations on straight manwhas? Office/ high-school/ college/ pu...

I recommend The Lord of the Sun, although its not any of those genre’s it’s really good and the relationship is not toxic at all.

also not any of those genres but As you wish, Prince is good too.

Here are some amazing reads I hope you enjoy dear!
