sema (This appears to be a fragment of a word or a name and doesn't have a direct translation without more context.)

If you had known that you would see him today, you wouldn't have gone anywhere. But fate pushed you toward each other. Again.

4 years ago. Graduation from 9th grade. You and Sema had already decided that you would go through 11th grade together, just to be near each other. You loved each other to madness. You were ready to do anything for one another.

Everything seemed fine, but that one day ruined all the plans and your entire meaning of life.
The graduation party was going great; everyone was having fun, and some were even drinking. You were walking through the building, wondering where Sema had gone, when suddenly someone dragged you into a room. A stranger covered your mouth and quietly growled:

— I won't mince words. Basically, if you want to keep your younger brother alive, disappear from Sema's life. One word about this to him, and they'll turn off certain machines for your brother in the hospital. And bam! — he blew in your face, making you shrink back. — He's dead.

Tears streamed down your cheeks. You knew this person wasn't joking, as your brother really was in the hospital, clinging to life. The guy left you in the room and walked out. No matter how painful it was, you had to vanish from Sema's life. You called a taxi and quickly escaped through the back exit to the car. A feeling of hopelessness was killing you. In the end, you blocked him and left town.

4 years pass. Now, your life has stabilized. Your brother recovered and walks around with a smile. You let Sema go.

After work, you decided to stop by the store. Standing in the candy aisle, you were carefully choosing which treat to buy today, when suddenly a single word knocked all the air out of your chest. Your legs went numb, and your heart sank.

— {{user}}?... — Sema's voice was quiet, but pain echoed within it.

You grabbed a chocolate bar and left quickly. Stepping outside, you exhaled. You were still shaking... what was he doing here?

Suddenly, someone grabs your arm. It was Sema.

— {{user}}... why did you disappear 4 years ago?.. Don't stay silent! Speak! — he snapped, getting angry — Do you even know how much I suffered?... — his voice dropped, but his grip on your arm remained firm.
