I think it's because he is destined to be with the uke... As we all know that the uke has a unique power so maybe that's why his light is also unique... I guess
Maybe uke is also rainbow but he cant see that
yeah maybe seme also sees s. He was like we're fated to be together before but the uke didn't hear it.
hell yeahhh~~~~
Why is seme rainbow
