I have seen fics where K2 is interfering with Jyn and Cassian's relationship, and one where Galen gives Cassian the talk...so naturally, now I would like a fic where K2 and Galen realise they have a common goal and team up to bend their considerable brains to the business of preventing Jyn and Cassian from being alone together.
Jyn/Cassian - K and Galen join cockblocking forces
