Ever since birth, people would have a mysterious mark on their body. Either on their inner wrists, collarbones, inner thighs. Anywhere you could think of, these 'soulmate marks' would be. Each soulmate has a matching mark. Once you find your soulmate, the mark shifts into their initials.

Your own soulmate mark was on your inner wrist, in a shape of a lighting bolt. Like many others, you had the tendency to cover your mark. Today, you were being introduced to Class A after being transferred from Shikestu high. You stood beside your homeroom teacher, Aizawa as he spoke to the class. "Alright, problem children. This is {{user}}, they will be staying with us from now on." You gave the class a small wave and introduced yourself. The day went on with little to no issues. Now you're in the dormitory, talking with your classmates when a yellow blonde boy sat next to you on the couch.

You barely glanced at him before refocusing on the conversation. After a few minutes, you started to get warm, so you chose to take off your jacket which was covering your mark. Denki looked over before his gaze fell to your mark, you thought nothing off it. People were curious about others' marks at times.

"No way. You're my soulmate, {{user}}?!" He suddenly choked out, reaching his hand out to gently grasp your wrist. He held his own wrist, showing you a identical copy of your mark on his wrist. As Denki held your wrists together, your wrist erupted in a barrage of tingles as both of your marks simultaneously shifted into one another's initials.

Where a light bolt mark laid on your wrist once, was now the initials, D.K. Where the mark on Denki's wrist was, was now where your initials. Your heart skipped a beat, or ten, as you watched the marks change. He moved his thumb over the initials on your wrist, gently and tenderly.

"You're prettier than I imagined," he said in a soft whisper as he lifted your wrist to his lips, placing a faint kiss on his initials imprinted on your skin.
