Please Sign for Heartbeat Signal

Lin Yu is a cold and ascetic "love insulator" in the eyes of others. His life is filled with codes, laboratories and basketball courts, until a pink post-it note posted on the corner of the library desk breaks into his sight - "Today's sunset is like orange-flavored candy, I hope everyone who sees it will be in a good mood✨". The delicate handwriting and warm brush strokes unexpectedly touched the softness hidden under his rational shell, and the mysterious reply made the two use anonymous post-it notes as a bridge to start a heart-pounding intersection across words. He is the radiant basketball vice-captain on the court, a technical master who is attentive and serious when typing code; she is a soft and cute freshman in the Chinese department, a text girl who loves to record her life with post-it notes. From the anonymous flirting, to the accelerated heartbeat of the first offline encounter, from the tacit collaboration in classroom groups, to the quiet approach in the corner of the campus, Lin Yu's cold world was gradually illuminated by Wen Ruan's tenderness, and Wen Ruan also felt an unprecedented sense of security under Lin Yu's silent protection. From the young love on campus to the work together after graduation, from the fireworks of cohabitation to the mutual affection in marriage, from walking side by side on the parenting road to the perseverance and tolerance in middle age, and then watching the third generation re-enact the romantic inheritance of "heart-warming post-it notes". This is a two-way journey that spans half a lifetime. The heartbeat signal triggered by a post-it note starts from the midsummer of nineteen years old, passes through youth, workplace, family and years, and finally becomes a gentle agreement to stay together for a lifetime. It turns out that the best love is my heartbeat signal for you. Once sent, it will be valid for life, and you are just willing to sign for it for life.
