High school teacher Mu Yanxin accidentally entered Qi Xiao's tattoo shop in search of a student. The man raised his eyes and said lazily, "I've thought about where to get the tattoo." Her heartbeat started to beat from that moment on. Later, they became neighbors. He searched for her late at night, and she put plaster on his ears until they turned red. She was being followed, and he rushed to the rescue; while he was away on a business trip, she was counting the days until her return. When her heart beat uncontrollably, Mu Yanxin asked softly, "Should we get married?" Qi Xiao tattooed her image under the collarbone, the most painful part, and spent his whole life answering. Two people who were bound by the world finally became the gentlest destination in each other's eyes.
