As a sophomore in college, I woke up and went back to when I was four years old. Regarding this, I, who was born in a middle-class family and was still young and yet to fall in love, said that there seemed to be no grievances or grudges that needed to be changed through rebirth. Going through that time again, which was not long and not complicated, I just want to have a more beautiful life with the help of my more mature (although still shallow) experience.
