I've just read up to chapter 2 so far but here is my prediction: the reason the mc cannot see his own aura is because his aura is 'visible light' or white light which is the type of light that allows us to see in the day. the mc is a perfect match for the ml because the ml is 'rainbow' or in other words all the components of visible light when it is separated, so basically they have the same aura. I doubt this is correct but we will see.
Honestly after reading season 1 I just feel like the story isn't that good. The sex doesn't feel rewarding because the literally had sex before they developed any chemistry (and honestly I feel like they lack that, too). Also the ml is so annoying. He keeps dragging the mc away for no reason. Literally all the mc has to say to the silver and blue aura dudes is that they would be a good match and they will stop bothering you guys! Stop dragging your boyfriend away before he can tell them that!!! I couldn't even bare to read the rest of season 2 beyond the amusement fair episode bc I was so annoyed
