Introduction:
On the first day Lin Yin moved to 703, he heard the sound of a guitar next door.
There lived a tall girl in 704 who didn't like to talk much and practiced piano in the middle of the night.
Separated by a wall, they are each lovelorn and lonely.
The day Lin Yin knocked on the door, she just wanted to share half of the extra instant noodles she bought downstairs.
Unexpectedly, this knock would tell the story of the next five years.
Two girls, two lives, separated by a wall.
Some people are not destined to fall in love, but they will stay with each other for a lifetime.
