Ten Thousand Meters Above the Ground, the Secret Signal from the Tower

As a senior flight attendant, Lin Wanqing has long been accustomed to the pace of life at an altitude of 10,000 meters, but she has never forgotten the gentle male voice in the tower. Before each flight lands, that unique guidance voice always relaxes her tense nerves. Until an unexpected diversion, she finally met the owner of the voice at the control center - the calm and reserved air traffic controller Chen Yifeng. When he handed over a cup of hot cocoa, the delicate "L" shaped flowers on the cup made her heart skip a beat. Was this a coincidence, or had he already recognized her? A love story between the clouds and the ground, connected by radio waves, begins.
