just realized about something, You guys know how when Oikawa hurted his knee because he's been practicing volleyball too much. Well once when I was younger I used to love this one sport called gymnastic, I always practice my gmynastics at home and follow every yt gymnastic turorials. There was this one time where my kneck started to hurt, at first I thought nothing of it, but as time went by it started to hurt even more to the point I can't even turn my neck anymore. So of course I had to go somewhere to fix it, gladly it was fixed but after that I never do gymnastic ever again. This case is pretty similar to Oikawa's bad knee if you think about it, hurting ourselves with the sport we love. Only difference is, Oikawa didn't give up on his dreams to become a volleyball player while I gave up on my dream to become a gymnast and find other things I could do without moving that much.
