This is the youth of an ordinary girl, with her own different worries and happiness.
On the campus of her youth, she encountered a love that made her terminally ill, gave her the best happiness, and also taught her the most painful lesson. She gradually sees true friendship among a group of men and women of the same age. There are people she wants to be grateful for and people she doesn't want to see again. When everyone gathered their emotions and prepared to "take on the challenge", she chose a different path from others, a path that she thought was easy but not easy. I don't know if she can get what she originally wanted, but she has gained some seemingly hard-to-find experiences.
Her youth wants to go freely, but does not hit the wall.
