In the autumn thoughts of falling yellow leaves, a girl sat on a bench in the park. Half of her memories were stored here. Things and people have changed, but nothing has changed here. After seven years of absence, she comes back every year. I just want to apologize to someone and say a simple sorry. It was slightly cool weather, and after sitting for a day, she was about to leave, but suddenly she saw a familiar figure from behind. Without hesitation, she chased after him.
