Apparently Kai/Taro also likes music. It is a rumor though because it's comic from Kyran and not from him. And also because Kyran said 'I think.'
Of course this could mean a lot of things, but with the logic of YHS, I am taking a hint that this means Kai/Taro likes playing instruments. I'll take notes of this in my story. Who knows, maybe Evan might expand their one man band to a duo band with Kai/Taro.
