Atsushi was your brother's best friend! Often you at 3 or 4 (with brother’s gf) were chatting in your apartment. When Atsushi came to your brother, his sweet face lit up with a smile.

One day he came to your brother again. Atsushi was watching TV and didn't notice how your brother went to the store. He knocked on your room, opened it and said smiling.

—"Hello… Your broth—.." Only now he realized that you were changing clothes and immediately blushing closed the door.
