Yu Qian×Liang Yucheng
Everyone in Mingcheng No. 1 Middle School knew that Yu Qian, the eldest daughter of the Yu family, was pursuing Liang Yucheng. They thought it was just a temporary interest, but she didn't want to persist for several months.
"Liang Yucheng, just promise me."
Then when she had the opportunity to make up lessons, she confessed her love to the boy again and again, but the man never responded.
…
"I want to become a butterfly and be by your side after death."
"Aheng, don't cry..."
Concept: Regret is the norm in reality.
