>>60764777They were pretty close at the beginning, but once they got out of their debut periods they went their own ways. During this time Reine once talked about how even if they aren't close friends they all get along well together and are still supportive of each other. Once they started doing smoloro they seemed to get closer, and then 3D showcase increased that. They aren't as tight as the other gens and there are some less than stellar collabs/interactions but they have plenty of good moments together
