Why Do Anime Characters Hear Their Heartbeat So Loud?

My heartbeat is so steady that sometimes, I don't resemble a human being at all. The fluctuations in my heart rate are very small even though I might be sleeping, suffering from a fever, or losing too much blood. When I'm 18 years old, the Ziegler family admits me into a rehabilitation center. My new home is now a temperature-controlled intensive unit located on the top floor. Oh, Aiden Ziegler doesn't love me at all. It's merely because the one and only artificial heart present in this world—and also in his chest—needs to be fine-tuned with my own heartbeat as its primary frequency. If my heartbeat is steady, he gets to live. If not, he dies. Three months ago, a nurse accidentally took off one of the monitoring pads on my chest. Five minutes later, Aiden, who was ten thousand miles away, went through a temporary crash where his heart stopped. The next day, the third-party medical company filed for bankruptcy. Everyone who was involved in this incident got banned by the medical world. Because of that incident, all of the sounds get eradicated from the top floor. Even the elevator's chimes get muted when it reaches the top floor of the rehab center. Everything changes when Aiden flies to Iropa. That's when his fiancee, Mandy Sutherland, takes over the rehab center. As she flips through my medical bill of nine figures, she sneers at me. "So, the Zieglers are basically sustaining a loser who does nothing but gasps for breath while lying in bed, huh?" After that, Mandy tears off the monitoring pads and unplugs the sync line. Then, she forces me to get on a treadmill. "That'll be a six-mile run for you. You can forget about returning to the top floor if you can't finish the run." As I grip the handrails tightly, I can feel my heart rate turning erratic for the first time ever. It feels as though my heart is about to burst out of my chest. As soon as the alarm goes off, Mandy turns it off immediately. What she doesn't know is that Aiden's artificial heart has already gone crazy, just like mine, while he's stuck in a place that's 12 time zones away.

My roommate sets me up. She deliberately forces me into a death-trap survival game. As I shut my eyes and wait for death to take me, I realize that the game's bosses can read my mind. "Look at the blood spurting from this baby doll's neck. It's like a fountain of pee." The baby doll is baffled. It's about to launch its ultimate move, but it falters. "Man, look at how this guy is still sweeping the streets when he's so old. Does he not have a pension?" The old man is about to swallow me whole, but he suddenly gets a heart attack. An ambulance takes him away. "Oh, so this is the amusement park's owner. Oh, dear god, he's handsome, albeit a little skinny. I can send him flying with a kick!" The handsome owner's expression darkens. He instantly takes off his shirt to reveal his washboard abs. "Do you still think I'm skinny?"

At the party, my daughter deliberately raises a question to my husband. "Daddy, since Ms. Lloyd is having your baby, does that mean we'll be living with her in the future?" He places the nicely cut steak onto my plate and answers softly, "Your mommy and I made a deal—whoever betrays first will disappear from the other's life. I can't afford for that to happen, darling, so this must stay a secret. Even when the baby is born, I will never let Mommy find out about them." Then, he signs to me, "I'll always love you." My eyes turn red-rimmed without him noticing. Little does he know, my hearing was restored a week ago. He doesn't realize I've learned about the mistress he's been hiding either. And he definitely doesn't know I've secretly bought a ticket to volunteer-teach in the Seru Plateau. All I have to do is wait for the paperwork to clear in seven days. Then, I'll disappear from his life for good.

Ayanna Cambor, the crush of my childhood friend, Dorian Harmon, makes fun of me for being a mute. She purposefully pours melted dark chocolate into my thermos. Then, she howls at the top of her lungs. "As a mute, you can't complain even when you swallow something bitter." Later on, Ayanna takes advantage of the situation by forcing me to stick my tongue out. She insists on making me show everyone whether or not a mute's tongue is different from a regular person's tongue. I look at Dorian instinctively. After all, he has promised me that as long as he's around, he won't let anyone bully me. But he merely shoots me a cold glance. "Just stick your tongue out and show it to Ayanna. It's not anything major to cry over." I can only hold my tears back as I quietly conceal the school transfer application that I've just received. It's true that transferring schools is no big deal. In that case, there's no need for Dorian to know about it.

Everyone in class can hear my thoughts, but there's a catch—the "thoughts" they hear have been deliberately altered. During the exam, while I swiftly fill out the answer sheet, the rest of the class stays put. They eagerly wait to hear the answers in my head. [The answer for this is C, of course. These questions are exactly the same as the ones Ms. Clarke revealed to me. I'm going to be the top student again without even breaking a sweat!] Everyone else immediately copy my answers. Ultimately, apart from me, they all end up failing the exam. During our swimming class, my leg cramps, and I start sinking underwater. I try to scream for help, but my classmates hear something entirely different in my head. [I'm going to act like I'm drowning and see who's the idiot who jumps in to save me. Hahaha!] In the end, they all watch indifferently as I drown. My eyes open again. I've gone back in time to the day of the exam. This time, I can also hear these "thoughts" of mine that have been altered.

My older sister, Lucy Wheeler, is an extremely sensitive person. She'll burst into tears immediately if her doll is dirty or if a cream puff bursts in advance. In order to maintain peace in the household, my parents will fulfill any of Lucy's wishes endlessly. Since she doesn't like me at all, my parents don't hesitate to kick me back to my grandparents' home in the countryside. Later on, Grandpa and Grandma pass away one after the other, leaving me with no choice but to go home to my parents and Lucy. That's when everyone sets up 3672 house rules for me to follow. Since Lucy loves blueberries, I'm not allowed to touch any of them. Since Lucy loves dresses, I'm not allowed to look prettier than her. After undergoing 20 years of torment, I end up contracting breast cancer, resulting in my tragic death. When I open my eyes again, I've returned to the first day I've gotten home after my grandparents' passing. Lucy is extremely sensitive, right? Well then, I'd like to see which one's the more superior weapon—her tears or my fists!
