Main plot (highlights):
The story tells the story of Lu Qinghe, a top escape room designer who unexpectedly became a father at a low point in his life and raised a four-year-old daughter who fell from the sky alone. He has no golden fingers and only relies on his extraordinary logical thinking, creativity and hands-on ability as a designer to turn the boring parenting life into interesting "puzzle games". He designed unique educational toys for his daughter and created a family version of "breaking through" daily life. He unexpectedly became popular on the Internet and became a highly sought-after "logic flow" parenting blogger, and his career also ushered in a second spring. Just when the life of father and daughter was on the right track, his ex-wife, Su Wanxing, the world's top surgeon, who had disappeared for many years, suddenly returned to China. Facing the quirky, smart and independent daughter raised by her ex-husband, and the man who became more attractive than before, Su Wanxing fell into the dilemma of "who am I, where am I, and how should I blend in with them?" The main line of the novel revolves around the process of the three people going from strangers, conflicts to running-in, and finally re-establishing a family. The highlight is how the male protagonist uses the thinking of a "secret room designer" to solve various parenting problems and family crises, as well as the fierce collision and final reconciliation between the male and female protagonists due to differences in concepts.
