As i told you in the comment that i make an idea of illustration for the story so the idea is:
In this scene, Oikawa, the talented but anxious volleyball captain, stands a little ways off from his friends as he gets ready to confess his feelings to Yuki. His friends, Makki, Mattsun, and Iwaizumi, are all gathered around him, each contributing some form of encouragement or playful teasing, while Kuroda, the team's manager, watches from the bench with an amused sort of curiosity. The gym, still energized from practice, provides a warm backdrop with volleyballs scattered and sunlight streaming in. Or the team could be trying to come up with ridiculously creative ways to help Oikawa, therefore showing their camaraderie and support. All in one, this combines the vulnerability of Oikawa, the liveliness of the team dynamics, and the bittersweet tension of the heartfelt confession.
I hope you like this idea and if you want any customization in this idea so i can do it and if you like it so we can discuss it more .
