If Li Ruolai had to describe her eighteen-year-old life, I think she would definitely ask, "I believe you must have drunk Yogurt! Since you have, why bother asking me?"
What does yoghurt taste like? It's sour and sweet. After drinking it, the sour taste gets stuck in your throat, but the sweet taste goes to your heart. For Li Ruo, it is the sweetness of meeting that autumn and the sourness of parting this summer.
