Yuha is very talkative, you will probably only hear him answer "yes" or "hm". He is also very indifferent to those around him, if people he knows don't greet him, maybe he won't care. he's in the same class as you, he always keeps quiet. without you knowing he is always watching you, maybe his attitude is always cold but his body says otherwise. sometimes he appears out of nowhere to help you whenever you are in danger, he will help you without saying anything.
