A/N: The story continues :D

"I guess there is something going on with Ayase." Kyousuke thought. Why would such a perfect girl like her have bruises? And really, seeing her so weak today after jogging just a bit, really did not seem like Ayase. After theorizing a bit about what might be the cause of those bruises, Kyousuke decided to ask her about it. Perfectly timed, Ayase walked into the kitchen where Kyousuke was eating dinner and sat down opposite of him, grabbing a plate of food for herself. She did look much better now but was still a bit pale. Kyousuke decided, that now would be the time to ask.
"Hey Ayase", he started the conversation.
"Ghn, huh, what is it, Onii-san?" she said while finishing her food.
Kyousuke started his advance to find out what was wrong with Ayase "Uhm, how do I start this.. I have been wondering today... You looked really sick when you got here and are still not completely back to normal, as far as I can see, and...well.. I saw bruises on your arms after you showered. You said that you canceled all of your appointments, but Kirino told me that you told the manager that you had ... trouble ...so.. am I interpreting too much into this or are you really having trouble somewhere or with someone that I should know of? You know, you can tell me anything." Kyousuke's face showed his concern. Suddenly, Ayase had a haunted look on her face and turned away from Kyousuke, covering her shoulders with her hands.
"Don't worry Kyousuke, there is nothing going on with me" Ayase looked back up at him and met his gaze with a light smile "Really, I just happened fall down in my room after I turned out the light. That's all. Nothing to worry about, I promise." Still smiling, or trying to, Ayase took her half-empty plate and threw the rest away.
"Well, I guess I'm done here for today. I will come back tomorrow. Keep on studying and don't go to bed too late." Ayase said as she left the living room. Kyousuke stood up while Ayase headed for the door of the apartment but she was too fast and had already put on her shoes and was almost out of the door when he reached the door.
"Ayase, really everything fine with you?" he had to raise his voice since she was already hurrying down the stairs.
"Yes, yes, I am fine. Really. Good night, Onii-san" Ayase called out.
"Good night, Ayase..." Kyousuke said even though she was already around the corner. He went back to finish his food and then study a bit more before he went to bed. There he spent quiet some time recalling everything that happened today and trying to make sense of it.
"Ayase never lies. She absolutely hates lying, maybe even more than she hates me. But her reaction today seemed weird for someone without problems as well as the 'falling in her room' excuse, they just don't fit. Well, maybe Kirino will notice something tomorrow. I don't want to be too annoying because her help really makes everything a lot easier here."
He then fell asleep, dreaming of his lovely angel Ayase-tan preparing his favorite food.

Kyousuke suddenly woke up to the sound of his phone ringing. He looked at the display on the outside of the phone and saw that it was Kirino who is calling. "What could she want so early in the morning?" he asked himself while picking up the phone.

...
"Hey Kirino, what is wrong? You woke me up, there'd better be a good reason for you to call me now."
"Hey Kyousuke. When did Ayase go home yesterday? How did she look? Was she all right?" Kirino asked in a hurry.
"Calm down. She went home...around 7 o'clock I think. She looked sick, but seemed fine overall. Or wait. She said she was fine, but actually did not look fine. She had bruises on her arms and was in a bad condition in general. Why are you asking all of this though? Can't you just ask her all of this herself?"
"She is not here! Ayase is not in school and she never misses a single day!" Kirino almost shouted into her cell phone
"Not there? Well, maybe she is sick. She looked pretty sick yesterday actually, I did not want to disturb you without a reason. Call her maybe and see what is going on. I'm sorry, I'm really really tired. Just let me sleep a bit more and be sure to message me when she is in school. Everything is going to be alright."
"I really worry about her. But okay, you never care anyways so go back to sleep and keep sleeping. Forever."
"I worry about her as well. I will ask her what is wrong when she gets here okay?"
...

Later, Kyousuke got a text message from Kirino saying that Ayase finally arrived at school. Apparently she just ran a little late, or that is what she claimed. Still a bit worried, Kyousuke ate some leftovers from yesterday and went back to his room to study a bit more.

A/N: Not really a cliffhanger here, I thought it still may be a good point to end this chapter. See you in the next one hopefully :)
