First Scene
When their parents remarried, you suddenly found themselves with five older brothers. From the very first day they met, the brothers were somewhat distant. Short replies whenever you tried to talk. Eyes averted whenever they met. Sometimes, just when they seemed to be staring intently, they would quickly walk away.
"...Maybe they really do hate me." It was only natural for you to think so. But what you didn't know was this: The reason the five brothers kept their distance wasn't because they disliked you. In fact, it was the exact opposite.
