Clay Harbor won people over with his sweet personality on Becca Kufrins season of The Bachelorette . Now, the former NFL player turned reality TV star is on Bachelor in Paradise , and hes still a total teddy bear.

While Clay has been pretty steady with Nicole Lopez-Alvar on BiP, theres apparently some drama coming down the pipeline. A preview for Tuesday nights episode reveals that his ex-girlfriend and fellow Bachelor Nation star Angela Amezcua (who appeared on Nick Vialls season of The Bachelor) is coming back for the wedding of former BiP stars Krystal Nielson and Chris Randone .

And, in the clip, it looks like Clay still has feelings for Angela. "Its not like a light switch," he says in a voice over. "You cant turn it off and on." You can also hear Tayshia Adams say, "Clay chose Angela over Nicole last night. He needs to man up." And then, the clip shows Clay say to Angela, "I still do care about you a lot."

While it's still unclear what exactly goes down in Paradise's latest love triangle, one thing's for sure: This is going to be so good!

But unlike the ex-couple's reunion tonight, Clay and Angelas relationship didnt go down in front of the cameras, so you might be a little fuzzy on the details. Heres what you need to know about Clay and Angela's relationship history:

Clay and Angela made things Instagram official in September 2018.

The couple first went public last fall when they shared pics of each other on Instagram. "What do the kids call it? Woman crush Wednesday? Welp heres mine," Clay adorably captioned a shot of himself and Angela.

The Bachelor Nation couple was set up by a fellow BiP star.

Chris first introduced Angela and Clay, after starring with Angela on season five of Bachelor in Paradise , according to Us Weekly . Apparently, Angela got things started after she told Chris she was interested in Clay.

Speaking of matchmaker Chris, here's what you need to know about his wedding to Krystal:

They were pretty serious.

Angela hinted last October that the two were thinking of moving in together. "Im still in South Carolina, but before Paradise, I was maybe gonna move to Nashville, and thats still kind of the plan. But I dont know," she said during the October 1 episode of The Ben & Ashley I. Almost Famous Podcast . "Were talking, theres been some things that were talking about. Its great because our schedules are super flexible right now, so its kind of like anything is a possibility at this point."

"If he gets picked up, then I can kind of go wherever he gets picked up or whatever, Angela continued, referencing Clay getting drafted by an NFL team. (He was a free agent in 2018 after spending years with various teams.) "So its kind of a perfect time. Like, I feel like timing is always very important in a relationship, and I feel like the timing is right for us right now."

...Just before Bachelor in Paradise filming started.

Yep, mere weeks after Clay and Angela called it quits, he left to film BiP. That timing's a bit suspicioussomething Annaliese Puccini, who is friends with Angela and appeared on BiP season six, called out, telling Clay that she thought it was too soon for him to date again.

Will Clay and Angela rekindle their romance after tonight's fiery episode? Recent spoilers from Reality Steve say that Nicole and Clay arent together anymore, so its a definite possibility.
