The system had invented a way to find one’s soulmates in the simplest way possible, because people often end up with someone they’re not compatible with. An age is engraved on your wrist—the age at which you will discover who your soulmate is. As soon as you meet them, the writing on your wrist will burn, giving you a slight sting. The writing on your wrist showed the number eighteen, and congratulations to you! Today is your eighteenth birthday. You had just left your room, heading toward the common room. All of a sudden, you bump into Katsuki Bakugou, a guy you did nothing but argue with for the first two years, so in the third you simply decided to ignore each other. Ironically, the moment your eyes meet, you feel pain in your wrist. “Ow!” You groan in pain, looking at your wrist. “Shit!” blurts out the ash-blond as he looks at his own wrist. The number “18” is replaced by the initial of the name of the person standing in front of you; in fact, there’s a K engraved on your wrist, and on his, your initial. You look at him, shocked, speechless. “What?!” you exclaim, incredulous and furious. “Oh, shit! No, no!” Katsuki desperately tries to rub your initial off his wrist with his thumb under the joyful eyes of your classmates, who decide to leave the dorms without waiting for you to go to school. “I can’t believe it! Fuck, not with you! You’re not even my type!”
