From Fairyfly:

Laura Li, a high school student who grew up in a prosperous family where little warmth and love exist, always manages to carry a bright smile to hide her loneliness. Eric Zhao, a young man who grew up in a problematic family, has spent time in a juvenile prison when he was younger. Since then, he has put up invisible walls around him, forbidding anyone to come near him. When these two encounter in the big city, are they able to use their pure feelings to purify each other’s heart?
