I don’t think I have talked about this before, so I can outline the details now!
By the time the game plot kicks off, there’s definitely been a tension of sorts between the three for a while. Leon is extremely busy as Champion, so starting a relationship is something he simply doesn’t have time for, not to mention Rose wouldn’t approve since it’d kick off a whole new series of publicity issues to manage. So Leon does sometimes consider relationships, but only really in the abstract. It’s something has no experience with. Raihan is aware of this and is angry about it, but also keeps his own feelings for Leon private since he doesn’t want to make things even more difficult for his friend and rival. Piers, however, is aware of all of Raihan’s woes because the two are friends-with-benefits and Raihan likes to complain to him, haha. Piers is starting to get a bit fed up with the situation as well, though. He understands the situation, but he’d rather Raihan stop being indecisive about their own relationship (keep it casual, try for something more, or just break things off) so Piers can get on with his life knowing exactly where they stand.
After Leon loses the Championship to Victor and Rose is detained, however, suddenly the factors keeping things in that sort of stasis are suddenly removed, and Leon is now free to pursue any romantic pursuits he desires without Rose breathing down his neck about it or having to rush off to some event (or at least less events now). Piers assumes this means that Raihan will break things off with him to woo Leon, but the pregnancy with the twins complicates matters and when he brings up the idea of breaking up to Raihan he’s actually very upset with the idea. The two agree to stay close at least for the sake of the babies, and in the meantime Raihan starts being more overt with his flirting towards Leon, who does actually pick up on it (since the feelings were mutual and he was looking for it). Leon is hesitant since he was aware of Raihan’s relationship with Piers, but when both of them express that they didn’t mind him being their third, Leon decides to try the whole relationship thing out, finally.
Things progress pretty slowly from there, just due to Leon’s own inexperience with dating, but the three grow very close over time, especially once Chelsea and Merrill are born (Leon adores them and is a natural as a dad). As Leon and Raihan grow closer, Piers assumes they’ll want it to be just the two of them growing forward and begins to distance himself, but both of them make it clear that he’s wanted as well – Raihan not wanting to lose what they’d had for so long and Leon having bonded a lot with him and still wanting to grow closer. At some point, they all move in together in Hammerlocke (maybe around when Nasrin is born?) and I think they marry sometime before Charlie is born. They have a second smaller home in Wyndon for when Leon needs to spend more time at work as well (and it’s closer to the recording studio Piers prefers). And that’s the story! By the fankid era they’re all very happy with each other and are doing well.
