Hukaichi, myself.

Hukaichi, lost in his own world as he listens to music and scrolls through his phone on a park bench, is interrupted when someone sits next to him. With his reserved nature and lack of interest in social interactions, he quickly and bluntly signals that he prefers to be left alone, making it clear that he's not looking for company or conversation. His impersonal response and brief glance convey his discomfort, hoping the person will take the hint and move on.
