Osamu Dazai has made many mistakes in life - who hasn't, honestly? - but he never could have assumed that sneaking out to hook up with his boyfriend would possibly be one of the worst mistakes of his life. It started normal, with the sixteen year old sneaking out of his window in the middle of the night, running across the street to Chuuya's house, and spending a few hours with him. Pretty average hangout.

Well, it all came crashing down when Osamu quite literally crashed down. As in, when sneaking back out Chuuya's window to go home, he slipped and fell to the ground from Chuuya's second story room. Osamu manages to push himself to land on his feet, crumpling only a second after landing when he heard - and felt - the very loud CRACK! of his leg breaking. Chuuya was by Osamu's side in an instant, who was curled up in a bush with a hand clamped over his mouth as he tried not to scream from the pain.

Chuuya tried running over to Osamu's house to get his dad, Mori, who he knew was a doctor, but Osamu stopped him, insisting that his dad can't know he snuck out to mess around with Chuuya and that they could fix it themselves. With Chuuya's help, he splinted his leg and just.. hoped it would fix itself. He had a slight limp (more than slight when he was alone), but he always brushed it off to everyone as having slightly twisted his ankle. Including to Mori.

Now, Mori was a doctor. And he knew his son. He knew there was something more going on, but he also knew that Osamu would shut him out if he pried. He tried to keep an eye on him, but it's hard when you take 12+ hour hospital shifts, so of course it seemed sudden when his baby started getting very sick. It started with a slight fever, then it spiraled until Osamu has incoherent and could barely walk... and that's when Mori saw it.

Noticing his son's constant limp that lasted for weeks turn into him not walking on said leg at all without crying out, paired with the horrible sudden illness, Mori forced Osamu's pant leg up and saw the state or his leg. It was red, hot to the touch, horrifically swollen, and leaking puss. Worst of all? He can see the bone in there. Osamu broke his leg-? When!? His son had been walking on a broken leg for god know's how long to the point it's gotten infected, and Mori just found out!?

Obviously, Mori rushed his feverish and incoherent son to the hospital, and after twelve sleepless hours of testing and just getting Osamu stable, the doctor informs Mori of the options. They could fix Osamu's leg, but it will take a very long time of healing and physical therapy, followed by a life filled with chronic pain and most likely a permantent limp... or they could amputate it.

He wanted to run it by Osamu before making a decision, but the boy was so horribly sick.. Mori had to make the decision, and ultimately decided that amputation was the best option. Mori could supervise the healing process and help Osamu through physical therapy once they find a prosthetic - and Mori will be buying him the best prosthetic out there. He would be there every step of the way, work be damned, and make up for missing something this big.

Chuuya must have had heard what had happened, because while Osamu was in surgery, Chuuya showed up to the hospital with flowers and told Mori everything. His son hid something this important because he was scared how Mori would react about him sneaking out. That... that really hurt Mori.

Within the day, Osamu was out of surgery, and Mori was by his side in an instant. He didn't sleep a wink for six excruciating hours, just staring at his son and wondering how he'll possibly break the news to him when he wakes up. Finally, Osamu stirs awake at four in the morning, his fever having finally gone down. The sun isn't even up yet, the room only illuminated by the bedside lamp and the beeping monitors. Mori was instantly squeezing Osamu's hand in gentle reassurances as he watches those pretty eyelashes flutter and finally, open.

"Baby, heyy." Mori coos softly, "How are you feeling?"
