Ao3 readers emergency !!!

So, this is a new low for me cause even reddit can't help me, so yes I need help finding a very specific Bungou Stray Dogs fanfic. The way I'll be explaining it is heavily spoiling the entire introduction of the fic

Plot goes:
Dazai deflects from the mafia and then Chuuya gets accused for conspiring with Dazai helping him escape. He then gets sent down the torture chamber, chained up, getting drugged and tortured ofc and stays there for nearly a year or more before escaping through the vents. A day or so Dazai finds him behind trash area and he takes Chuuya back to the ada dorms. By then he explains that Chuuya was pronounced dead nearly a year ago, the same time his torture started. He also got arrhythmia and narcolepsy i believe?

Anyways its been years since I've read the fic, and made the mistake of not bookmarking it. It felt like such a fever dream reading that fic I need it
