The heroine Yang Yiyi was abandoned by her sweetheart on the eve of her birthday. From then on, I got on a small train and started a college life of shopping, eating and drinking. He picked his feet and told jokes. The happiest thing is to skip school and sleep in. I planned to spend the rest of my college life lazily like this, but I didn't expect to meet him - that sinister guy who hollowed out the heroine's heart and filled her brain. Look at the sparks created by the hero and heroine! Whose love network captures whom? Who is trapped by whom and cannot escape?
