Twenty-one-year-old Gu Weiliang didn't know that she had met this very important person in her future life ten years ago, but her heart was still captured by him and his cat. Twenty-seven-year-old Xia Zifeng recognized her after meeting her several times and she was the girl who followed him with Coffee (the male protagonist's cat) and called him Brother Xia. But why did she think Coffee looked familiar but didn't recognize him? Coffee, who was less than one year old, finally got to know his teenage master's home and was sent to his grandma's house. They all said that his little master had to take the college entrance examination. What is the college entrance examination? But what troubled it even more was that one day a little girl came to the little master's grandma's house. Boring humans would ignore her, but she didn't even ask me what her name was and just called her Xiao Ke, Xiao Ke? But it's clearly called coffee! But it found that the little girl would play with it, help it clean the mud all over its body, and share its snacks with itself until she told itself that they were friends. When they met again, he smelled the familiar scent on her body and recognized her immediately. She still called him Xiaoke as soon as they met. This is their ten-year agreement.
