is more than 1 aura a sign of threesome or what

In the earlier chapters, the uke said that the auras are related to compatibility. Uke introduces people with the same aura color and those people have a happy ending. With this newcomer, his aura has two colors so I assumed that he is also compatible with two people, hence the threesome idea. (=・ω・=)
