If Yu Yu hadn't picked up the pocket watch, she would never have known that there was someone in this world who loved her.
Yu Yu has been wronged since childhood. His father did not love his mother, and he was often bullied on campus, but Yu Yu just endured it and did not say anything.
Because in her opinion, she doesn't trust anyone, including her parents.
Until she met Su Cheng, who was very good. He made up for the love that Yu Yu had lost over the years, and gave Yu Yu a lot of warmth.
But Yu Yu also gets tired. She suffered from depression due to long-term bullying. Later, even taking medicine didn't work. The doctor could only advise Yu Yu to relax and try to be more cheerful, but Yu Yu couldn't be happy no matter what.
In the end, Yu Yu was overwhelmed and finally jumped off the building and left the world.
Su Cheng knew that his little fish was gone and he couldn't live without Yu Yu. He couldn't live without Yu Yu.
After taking care of Yu Yu's funeral, Su Cheng also chose the same way to end his life. He wanted to fall into Yu Yu's world and find Yu Yu.
Intention: Study hard and be happy every day
