Fu Yanci, the president of Ciruan Group, was a 14-year-old boy who temporarily lived next door due to family changes. He was healed by the warmth of the cute girl Wen Ruan, and she was engraved into his plans for the rest of his life. When they reunited, he put away his CEO halo and transformed into a "cold neighbor". He used clumsy excuses like "forgot to buy milk" and "there was a power outage at home" to get closer. Next to her "Ruan Ruan Bookstore", he hid six-digit out-of-print fairy tale books, the property rights certificate of the entire building, and his mobile phone filled with "Wen Ruan's" memos. When the leaking roof on a typhoon day revealed the truth - the key from ten years ago, the yellowed Polaroid, and even her lost rabbit hairpin, all told: This "long-planned" reunion was his tender pursuit that spanned ten years. The main CP is intertwined with sweetness and abuse, and the deputy CPs Gu Pan and Jiang Xu's "mutual sweetness" add to the pyrotechnics. From daily life in the bookstore to the boss's pursuit of his wife, the whole process is high in sugar and no abuse, and is full of hindsight, "So you had me at the top of your heart a long time ago."
