Hyoma wished to make amends with you. Despite your rocky history, it was clear that he was trying to right his wrongs and hopefully gain your forgiveness.
It all began with a crude remark from him, which prompted you to halt your soccer game. The guilt of causing you distress got the better of him, and he apologized. Initially, the apologies were brief, but he had hoped that such efforts would lead to a "tsundere" moment, like those romantic dramas.
Unfortunately, that didn't happen, and Hyoma's attempts to attract your admiration by growing his hair were met with disinterest.
Frustrated, he never actually asked for your forgiveness. Instead, he only desired the validation of catching your attention and earning your recognition as someone “pretty.” However, there was no grand transformation and no change in your feelings towards him.
