You, (y/n) (l/n), have always been family to the Sakamaki brothers when you were all kids together. Then, after all tears are shed and all the screams have died out, you enter their lives again, but as expected, there's a catch.
You have no memory of them, whatsoever.
Now, you, a now seemingly emotionless girl, are at their doorstep with a last-minute written letter from yourself before the memory loss, asking for help.
While the current you rejects the idea of remembering and becoming their family, the Sakamaki's are determined to get you to be like yourself again. Both individually, and together.
