OT3s where they’ve all been friends for a long time, but when Muse A and Muse B start dating they both realize that things aren’t the same without Muse C and they both want to date Muse C too.
OT3s where Muse A and Muse B used to date, and broke up long before Muse C comes along, but once Muse A starts to date them, Muse B realises they never really got over them and wants them back, with Muse C as an added bonus.
OT3s where Muse A and Muse B have been best friends forever, but they don’t get to spend as much time together now that Muse C is dating one of them. At least not until someone jokingly suggests that Muse C date both of them, and the suggestion becomes a reality.
OT3s where Muse A and Muse B are best friends. Muse A is dating Muse C, but Muse C is also attracted to Muse B. Which is awkward until Muse C finds out that Muse B is attracted to both Muse C and Muse A. Now the only question for Muse C is how to get both Muse A and Muse B into bed together.
OT3s where Muse A and Muse C are dating, but Muse C accidentally stumbles into Muse B’s bed while intoxicated. Muse C is horrified by their mistake the next morning until Muse B reveals that nothing happened and that Muse A used to date them anyway. Now Muse C can’t help but wonder what might have happened between them and Muse B. Even though they are perfectly happy with Muse A, they can’t stop having fantasies about Muse B and avoiding them as a result. Once Muse A finds out Muse C’s secret fantasy, they get together with Muse B and decide to surprise Muse C with it.
OT3s where Muse A and Muse B have been friends forever and they share everything, so when they meet Muse C, it only makes sense to them to share Muse C too. Unfortunately Muse C is not as on board with the idea, so Muse A and Muse B set out to seduce Muse C together.
OT3s where Muse A and Muse B have few things in common, namely: they both hate each other, they’re both dating Muse C, and neither of them knows it. Once they find out that Muse C is dating both of them, they try to make Muse C choose. Muse C refuses to choose between Muse A and Muse B and says they’re going to date both of them or neither of them. Neither Muse A or Muse B is willing to give up Muse C, so they both grudgingly agree. Unfortunately for them, Muse C insists that they at least try and get along, and unwilling to lose them they start spending time together to see why Muse C thinks the other one is so great.
OT3s where Muse A and Muse B met at a party and hit it off, but they got separated over the course of the night and Muse B ended up going home with Muse C. Which would be fine, except Muse B is now pregnant and when she goes to tell Muse C, Muse A answers the door. Apparently Muse A and Muse C are roommates/best friends. Can the three of them work something out before the baby arrives?
OT3s where Muse A and Muse B have been friends for a while, but Muse B doesn’t realize they’ve developed feelings for Muse A until they’re already dating Muse C, They decide to try and break the two of them up, but along the way they develop an attraction to Muse C as well. Now Muse B wants both of them, but isn’t sure how to tell them until Muse C hits on them in front of Muse A and Muse A is encouraging instead of jealous. Maybe this won’t be so difficult after all.
