He had backstroke for days when no one else did- Makoto x reader

Interrogation

When we arrive at the station I am brought into a room and asked to sit down. The room is huge, it has a grey desk and two grey chairs, one of which I was sitting on. The walls were a bright white. After a few minutes of sitting in the room alone an officer came in. "Hello (y/n), my name is Mike Ken, but you can call me Mike. I just want to ask you a few questions abut yours and Makoto's relationship." I nod. A few officers come in with a polygraph test, they hook me up and the test begins. "how long have you known Makoto?" I know this answer like the back of my hand "6 years" he moves on to the next question"where were you when Kou was murdered?" I look down and start to bawl "right infront of her. I tried to revive her but she was gone." He turns his head "hm,so you were there? That's interesting. Where were you when Rei was murdered?" I try to recall where I was "I was with Makoto when he got a call from Haru telling us the news." The officer nods "oh, I see. Now Haru was the most recent murder as I understand. Now where were you when this happened?"  I look up at the officer "I was with Makoto." The officer looked suspicious. "the way I see it you and Makoto seem to spend alot of time together so you would have time to collaborate the ways to kill your friends and then run from the crime scene. Is my hunch correct?" I am shocked "are you accusing me and Makoto of killing our friends?" the officer nods "that's exactly what I am saying." I stand up furiously "I would never kill my friends they are the best thing that has ever happened to me, and I would never kill them. And if your stupid Polygraph says otherwise it is wrong!And I would like to go home now." The officer stood up "now (y/n) we can't let you go home. You have to stay at the station until our investigation is complete." The officer starts to pack up and leave "wait, I have proof it wasn't me!" he turns around and looks at me "where is your proof" I point to my pocket "in my pocket is a letter I got today from the murderers." The officer comes over and reaches in my pocket and grabs the note and leaves the room. I sit in the corner of the room and start to cry into my hands "Makoto where are you? Come back! I miss you! Makoto I'm sorry that I didn't tell you abut the note I did it for your own good though. I knew if I told you they would kill you and I would never be able to live with myself if you died and I could have saved you! Come back Makoto! I love you!" after my rant I lie down on the cold concrete floor and fall a sleep in the cold and scary place that I might haveto live the rest of my life in if they don't believe me.
