[Double cleanliness + sweet pet + sister-brother love + dark belly + secret love + 3-year age difference] Her parents passed away and she raised her grandmother with Alzheimer's disease alone. Su Wan's youth was full of tolerance and strength, but she was bullied because of her family background and status as a top student. Until the appearance of Lu Zhiyan, the academic god who skipped a grade, broke all her embarrassment. He was a cold and distant flower on campus. He was indifferent to the outside world but was gentle and paranoid towards her. He silently guarded her for a whole year, but quietly left after the college entrance examination, leaving behind endless regrets.

With his lifelong preference, he healed all her scars and made up for the regrets of his youth.
