The first one is the shallowest yet most obvious reason
they look hot af together.
The second one is that their chemistry is off the charts. If you can't see the amount of chemistry klaus and Hayley have together you are either blind on in strong denial. They have the most chemistry of all the ships in TO and I'm not saying that to be bias either. I just truly believe that they have amazing chemistry. And not just any chemistry but a steamy one which is why add to their hotness level as a couple.
The chemistry between these two seems to is natural and you can tell that they care for each other and that they are attracted to each other, even if that's not what they are suppose to be. You just can't hide it. The way both look at each other is A+ chemistry.
Si okay looking at pictures only and you can see it. We all know chemistry is an important part of any relationship.

That's it for now 💕👑
