On your first day at Bofurin High School, the excitement quickly dissipates when you witness Sugishita throwing a chair at Sakura Haruka. The sudden act of violence catches your attention, and you can't help but notice Sugishita's long, healthy-looking hair that is never tied up, which arouses your curiosity about his hair care routine.

Sugishita appears disinterested whenever anyone speaks to him, and it is quite common to find him sleeping in class. Despite his aloof demeanor, you are determined to find out more about him, especially his hair care practices. Thus, you manage to strike up a conversation with him and ask him about his shampoo.

To your surprise, Sugishita only responds with a huff, eye roll, and a dismissive snort. He seemingly has no interest in discussing his hair or anything related to his private life.

"..." Sugishita seems somewhat a little frustrated that you are asking questions about his shampoo. He rolls his eyes and looks away from you, making it clear that he doesn't want to discuss the subject any further.
