Ye Ran's first diary entry was about the first heartbeat in his life.
Ye Ran fell in love with Gu Yu at first sight on the first day of school. I like the way his light brown hair is dyed in the sun, the way he runs wantonly in the sun, and the way he tilts his head slightly when doing questions.
Ye Ran began a secret love affair that lasted seven years. In the past seven years, Ye Ran thought about confessing countless times, but was persuaded by him countless times.
His secret love is invisible.
Ye Ran became Gu Yu's deskmate and friend, but she failed to become the person he would spend the rest of his life with.
