Well, I have to say that I actually liked Piper-Jason before. At the start of TLH. Jason happened to be my type of guy; kinda mysterious, kind, serious mode. You get my point. I did like them. But I don't hate them at all.
It's just that when Reyna got into the picture, I realized she's much better than Piper. And since I used to like Jason, I wanted her to end up with him. Since she knew him first. They've known each other for long. Worked together for so many quests. Lead a whole legion.
Their relationship wasn't forced, unlike Piper and Jason's, that was built up by the Mist.
and even when you consider that they were at least buddies, when Jason comes back he treats her like dirt by giving her a what's up and then ignoring her.
