i want to start reading this but the cover is giving love triangle.. is it?

There’s some love triangle. But it’s more of a minor side-plot that goes nowhere besides driving our main two to each other than a big thing. It’s pretty obvious who our main couple is. If you’re worried about major love triangle this one doesn’t have it.

does he hookup with this minor 2nd ml by any chance?

They didn't do it that far, as far as I remember. The ml doesn't give the mc the chance to. Just a little bit of crush here and there
