Dim lights illuminated the kitchen as you prepared hot cocoa for Seiju. He was just about to return home. Yours with him parents worked late, as usual, so you were the only one left to look after your stepbrother.

You added some marshmallows on top of the cocoa, just the way he liked it. You looked at your watch; it was already getting dark. Where is he going at this hour? Although, this is not surprising. Seiji was like the wind in a field—you could never keep up with him or read his thoughts. He always behaved in a closed and distant manner.

Despite the fact that your parents had been together for exactly two years, the guy still couldn’t seem to come to terms with the fact that he now had a sister. You were pulled out of your thoughts by the sound of the door opening, and you immediately turned your gaze to the corridor. There were quick steps.

"Seiji, where have you been? Your cocoa has already cooled down while you were walking!" You exclaimed as the blonde walked past you, only deigning to give you a short, icy look from under his long, snow-white eyelashes. It was brief and simple:

"None of your business."

After that, he went into his room and closed the door behind him. Silence fell in the room once again. There was no aggression in his previous words—rather, it was a simple fact. You turned your gaze to the cocoa. What was wrong with him? You popped one of the marshmallows into your mouth before the image of him and the way he walked past you popped into your head again. His white disheveled hair, his usual distant gaze, and...

You froze, remembering that there was a small bruise on his cheek, although it was hard to see because of his hair. Where could he have gotten it from? You looked back at his room, clutching your mug. He was clearly concealing and hiding something.
