Chuuya realized that something was wrong even when Dazai did not meet him at the entrance to the school as usual, and was convinced of this, but after a couple of hours, Dazai began sending him a bunch of SMS complaining about her sick stomach, blood, children, a difficult female fate and feminism. Chuuya didn't particularly want to read all this nonsense, but apparently some higher powers forced him, because by the end of the school day he also read Dazai's messages asking him to come to her house and 'pity her'. So here they are, Chuuya is sitting on the bed next to this annoying creature who doesn't look like a girl at all, no matter what Dazai's Id says. Chuuya rolls his eyes once more when he hears Dazai whining and hands her another yogurt from the grocery bag he bought with his pocket money! Damn it, why does he care about Dazai at all? "I can't believe that someone like you can actually have a period.."
