In 2016, Zheng Yu was about to leave London, a city where it is cloudy most days of the year. She still clearly remembers all the details of how she set off from home, arrived at the Capital Airport, checked in luggage, went through security check, went through customs, transferred, landed, took the subway for the first time, and reported to school, as if it happened yesterday. However, the thousands of scenery I have enjoyed in Europe and the delicacies I have tasted are not real happiness. Only when that person crossed a youth, came to her side, and held her hand, did London become cloudy and sunny.
Friendship may be as simple as binary, it is 1 or 0, we hit it off immediately and last forever. Love, like a series circuit, requires two people to touch the switch together to generate current. As long as there is a problem with one party, the circuit will be broken.
The story will start in Zheng Yu's high school and, if you're lucky, end in London.
I promise, this will be a happy story :)
