Looking for Books with Male MCs and Absolutely No Romance.

Hi everyone! I’m looking for some book recommendations with a male main character and no romance at all.

I don’t mind if the side characters have relationships, or if someone has a one-sided crush on the MC, as long as he doesn’t reciprocate or get involved in anything romantic.

I usually enjoy stories where the MC takes on some kind of leader role or is thrown into a survival or adventure setting. Stuff like Lord of the Flies or Ender’s Game really hits the spot or even books like maze runner(yes, I know it has a bit of romance in later books).

But honestly, I’m open to anything as long as there’s zero romance involving the main character. Feel free to drop any recs you think fit that vibe!

Please, I'd really appreciate the help. Im kind of in a slump right now and really want to get back into reading.

Thanks in advance for the recommendations everyone 😊.
