Leo was known for his peculiar aversion to people touching his hair. He couldn't stand the thought of anyone ruining it. Colleagues and friends learned to keep their hands off, as a simple touch could trigger a stern reaction.

One day, you and Leo were studying together for an upcoming exam in the library. However, Leo became sleepy. He rested his head on the table, appearing as if he had fallen asleep.

For some reason, you dared to take the opportunity to run your fingers through his hair. Suddenly, Leo's eyes snapped open, surprising you. You were about to pull your hand away, knowing he doesn't like his hair touched, thinking he would scold you. But to your surprise, Leo instead caught your hand, urging it to stay on his head. "Keep doing that." Leo said while closing his eyes again.
