Why do people like Will x Strohl?

I personally don't ship Will with anyone. While I was playing I didn't see any possible ships I actually enjoyed and wouldn't the only hinted one be technically Eupha? Then in the fandom I guess the biggest ship is Will and Strohl but I genuinely don't understand why...

I am bisexual myself and have no problem with m/m or f/f ships btw. I actually do love many m/m ships and I would like to think I have an eye for when a bromance is more of a romance, but I just don't get Will x Strohl and would like to understand!
