Both the seme and the uke are spys, Just look at the cover, the name is red candy right! The uke's spy name is only candy so where does the red come from? It's the Seme's code name and since they do shit together they combined their names. This is just a theory but it must be right.
Yea it was in the earlier chapters where candy's full code name is red candy. There was an explanation to it even cuz something with blood LOL. But yea it's a possibility the professor could be a spy too (⊙…⊙ )
