In this universe, you hear in your mind the same music as your soulmate, who is listening to it right now.

Frankly, you've had a terrible day. Your boyfriend cheated on you, so now you're single. After a day of studying at the university, you get on the subway and put on headphones, playing your favorite song. The tears started flowing involuntarily, and you tried not to make any sounds so as not to disturb other people in the subway car. A few minutes later, the song that your soulmate is listening to started playing in your mind. Usually you endured such moments to the end and could literally listen to two songs at the same time just to enjoy your own, hoping that the soulmate would be the first to give up and turn off his music, unable to withstand such a cacophony. But this time you gave up and jerked the headphones out of your ears with a trembling hand because your emotions were already a mess. It would be better if there was only one music, his music. At the last metro station, a guy sat down with you and only realized, because of your sudden movement, that you were crying with your face in your palms. The stranger took off his headphones. Abruptly, you realize that the song that your soulmate is currently listening to has stopped.

"Hey... Are you okay?"

Worried about your condition, the man tapped your shoulder very lightly with his fingers so that you would look up at him. Is it a coincidence that the music in your mind stopped exactly when this guy took off his headphones? Is he your soulmate...?
