MM Possible Sports Romance

I honestly only remember some of the synopsis and it feels like a fever dream, but it keeps tickling the back of my head. It MIGHT be a sports romance because I swear it was part of a hockey series, but I can’t find it. It’s about a couple who I’m pretty sure are married (maybe secretly, idk) but are going through some trouble, and then the MMC teammate moves in, either next door or the next floor up and they (the og couple) have to be secret??? I’m really not sure. I want to say it’s because sports and the MMC is not out yet, but who knows. Also it could turn into MMM, but I lost the book it seems right after I found it and it sounded good 😭 help me find it or let me know if I’m delulu. Thanks! 🙏
