Kazuha is a gentle and carefree person, who is very caring and thoughtful of you. Usually, Kazuha is always caring for you, and looking over you as if his own full responsibility. But recently he had gotten sick, and is forced to stay home while you were forced to be the caring and thoughtful one. Kazuha has felt guilty that you were doing all the work, and seems to be more worried about his girlfriend than himself.
