I'm desperate (lost ao3 fanfic)

There was this one fanfic I read like a year ago, and I've been looking for it for FOREVER. I went through my history on the website, I tried going through my history on my phone, but I had gotten a new phone since then. I've tried going through my bookmarks, I've tried finding it from using the tags, but no luck. So, now I'm asking anyone who may have heard of it or have read it themselves to help me find it.

It's an mha fanfic (I know, don't throw tomatoes). I can't remember if it was platonic or romantic, but it was surrounding izuku and katsuki. It was a 'what if' fanfic ofc.

So the story goes, from what I remember, Izuku gave up on his dream to be a hero and stopped showing up to school. Katsuki (keep in mind, he was still a shitty asshole to Izuku, but he got worried after Izuku stopped showing up to school) goes over to his house and tries to see what was going on. When he knocked on the door, Inko answered and she was distraught bc she couldn't get Izuku to eat, take a shower, talk, etc. He asks if he could talk to Izuku, and she lets him in.

He goes into Izuku's room, and tries to talk to him, but Izuku never responds. So Katsuki gets kind of aggressive, and he picks Izuku up and throws him into the bath tub and demands he take a shower so he can stop worrying his mom. Izuku still doesn't talk. But Inko barges in, and upset, she tells Katsuki to come back another time. So he does, and he brings Izuku his school work (?) and tries to get Izuku talking again.

Idk how long this goes on for, or how it gets to this next part, but Katsuki tries really hard to convince Izuku not to give up on being a hero. He even tries to get him into vigilante work, saying he's be a good sidekick, partner (?) for Katsuki and they can work side by side. I think Katsuki was just talking out of his ass, saying anything to get Izuku up, but Izuku really thought about it. So the next time Katsuki come over, Izuku is out of bed and writing stuff down in his journal.

I can't remember exactly what happens after this, but skip towards the end of the fanfic, they have a huge fight, and they end up in like a sewer tunnel at night, in the rain and they confess their feelings (not romantic, more like what they have on their mind). And I can't remember anything after that.

I know it's a long shot, and this might have been deleted by the creator or my memory might be way off. But if anything you've read is even remotely similar, drop the fic name and the author, so I can check it out. I will take anything you can give me PLS
