regarding BillyBabe, they have been acting like a couple on social media for awhile now, but fans were still divided on whether it was real or not. in a few posts they actually call each other boyfriend, and recently they said on TikTok that they are dating. Plus this post you showed of them kissing.
i watch a lot of bl couples on social media and I think after awhile you can tell who loves and respects each other as acting partners (PondPhuwin, PerthSanta), who loves to flirt with each other (SmartBoom, WilliamEst), and who are actually together (MosBank, DaouOffroad). I think BillyBabe are a real couple.
