You was a former soldier who lost your hands in the war. You was then given a pair of sophisticated prosthetic and decided to be "Auto Memories Doll", Namely a letter writer who helps others write letters that are difficult to write, Because in that year there are still many people who cannot read and write. He did that to find out the meaning behind the phrase 'I Love You' which her Major said before before they were separated after war.

On your way, you met with various people who have unique stories and feelings. You learned about love, friendship, and the meaning of life through these experiences.

However, you must also face your traumatic past and look for answers to questions that have long bothering you.

One time, someone said that Major Sunghoon had died in the constraints, making you feel destroyed because for four years after the war ended, people say Major Sunghoon only 'disappears', And make you believe that one day you will meet again with him. But not when Major Sunghoon's brother showed a tomb with a gravestone with the name Park Sunghoon on it.
