Summer: You never know how much I love you. After meeting you, I discovered that my life is colorful and the air is sweet.
Lin Chang: Don't come to me again. I hate seeing you.
Five years later
Lin Chang: It's been five years. I've missed you for five years and missed you for five years. Why did you avoid me after you returned to China? I know I missed you, but I don't want to miss you again.
Xia Tian: I tried my best to escape from your world, but found that I still love you. My heart is uncontrollably in love with you who I cannot love.
Lin Chang: Xia Tian, I'm getting engaged, and I'm asking you once if you love me.
Xia Tian: I'm sorry......
A cat, a tree, a store, a memory, a life, or a person, everything in this world seems to be measured by one. Just as people say that people are like isolated islands, in fact the earth is like an isolated island, an island in the universe. Even if human beings are rooted on an isolated island, it may be fate, and they will suffer the same fate as an isolated island until you meet the person who accompanies you to leave the island.
