Ichika is a pharmacist in the pharmacy department of the county hospital. Her favorite hobby in her life is to sit down and watch TV dramas after get off work. Her biggest worry is being urged to get married by her own mother. Her best friend asked her why she didn't study clinical studies. She bit her straw and said, "The score is not enough." Until that day when she was crossing the square, a little boy whose throat was stuck by candy asked her to practice the Heimlich maneuver as muscle memory. The moment the candy flew out, the child cried out "Wow", and she collapsed on the ground, her back soaked and her heart beating like a drum. He raised his head and saw a man squatting in front of him against the light. The brow bones, bridge of the nose, and jawline all seemed to have been carefully measured. The man's voice was low: "Thank you, I'll take you to the hospital." She stood up and patted the dust on her trouser legs. She said softly, "It's okay" and turned away. Didn't even leave a name. She didn't know that the man was Lu Siqi, the president of Yimu Group. She had never said "thank you" to anyone so many times in her life. Little did he know that he went through the list of hospitals in the county that night, just to find a girl with a bruised knee. An accident, an encounter, a cold and noble man learned for the first time what it means to never forget.
