In the book, the supporting male lead is the older brother of the female lead. The supporting lead has a cold and desolate personality and is despised by the female lead due to his terminal illness. However, when the female lead acted viciously and was abandoned by everyone, he still protected her, sacrificing everything for her and even dying for her. Su Ci has transmigrated into the book, becoming a little rabbit raised by the supporting male lead, and she has discovered that her life is tied together with this terminally ill supporting male lead. After becoming a little rabbit, Su Ci can only sleep on the supporting male lead’s dusty bed every day, eat withered carrots, and guard against the female lead, who occasionally tries to pluck her rabbit fur. To turn back into a human, she needs to find ways to get close to him every day. The supporting male lead noticed that lately, his pet rabbit always wanted to kiss him. Until one night, he leaned down and kissed this soft little creature, and it unexpectedly transformed into a beautiful little fairy! … The female lead encountered trouble, so she went to look for the supporting male lead, whom she always looked down upon. Unexpectedly, the young man, who was previously poor, down on his luck, and nearing death, had become a scion of a wealthy family in a blink of an eye, and by his side was a girl as beautiful as a fairy. But what made her jealous was that the always-cold and aloof supporting male lead actually kissed that girl gently in front of everyone!
