Oikawa has his moments where he can be pretty dramatic, using over-the-top gestures when saying things like "I've got this, you guys!" to his teammates and "I'll never teach you, idiot!" to Kageyama (Not to mention his habit of doing peace signs~).
However, Oikawa's most meaningful gestures are always the most subtle.
When Iwaizumi was crying and questioning his worth as the team's ace after their loss against Shiratorizawa that put them out of the tournament and ended the third years' high school volleyball career, Oikawa patted his best friend on the back. It was a small and simple gesture, but it had a huge impact on Iwaizumi. When Oikawa had felt self doubt and pressure to do well, Iwaizumi had kept him in check and told him he wasn't alone out on the court. Oikawa returns the favor and through this gesture reassures Iwaizumi that he gave it his all out there and earned his title as the team's ace.
Oikawa's other small gestures not only bring reassurance to his teammates (especially his underclassmen) but bring our their skill by getting them fired up.
