Megumi getting a major knee surgery done and he hates every second of it. Being completely dependent on others for everything and when the painkillers wear off, the pain is suffocating. He'd be crying all day from it, barely able to move an inch without feeling like he was being stabbed in his leg from inside.

Having to ask someone to take him to the bathroom, helping him sit up and lay down because he couldn't do anything. After sometime everyone's telling him to try and walk so the blood flows and he can use his leg again. He keeps saying it hurts. But all he hears is "of course it does but thats how it will be and you have to move your leg".

So he tries. He really does try his best to hold back his tears, holding tightly on gojo while trying to take a step but he can't even straighten his leg completely. Gojo gets frustrated with him, thinks he's being overly sensitive.

But days later he has a high fever and everything just gets worse. Having to go to the ER in the middle of the night because he's practically dying from the pain, only to find out his wounds never healed and instead got infected.

He's back in the hospital and completely on bed rest. He'd recover properly after months, but his leg always being sensitive even after healing. He can't run, can't put all his weight on that one leg and not moving it around for too long hurts real bad.

Sometimes it gives out randomly, he'd trip or limp. It would hurt Sometimes for no reason, restless at night and not letting him get any rest.

He ends up regretting ever getting the surgery.
