Why does he have to come back? [Taehyung FF]

After the break up, you got depressed and stressed very much and you were slowly forgetting memories because of that until you forgot anything. Your name, your family, your friends and the one that you loved once. Luckily, your family helped you remember things but only your name and your family.

Your mom and dad decided that you and your mom will be moving back to Daegue while your dad and brother will be staying in Seoul.

They did that because they don't want for you to get hurt when you remember all the things that you had gone through, they don't want you to do stupid things that's why they are moving you away from Seoul where all the memories started.

Until you have to go back to Seoul because of some business of your mom.

What if the person that caused all this things come back? Will your memories recover or will your illness get worse?
