Four ordinary high school students and a mysterious transfer student face friendship, love, dreams and family conflicts together in their senior year of high school. Lin Ziqing struggles between studies and dreams, Zhou Jiayue strives to pursue self-worth, Song Yiran's relationship with friends becomes subtle due to his clear goals, Tang Xiaolu uses humor and food to relieve stress, and Yang Shuyao becomes a breath of fresh air in their lives. The five people began to get closer to each other amidst the hilarious laughter, and grew up little by little amidst differences and misunderstandings - the college entrance examination, family changes, obstacles in pursuing dreams, secret love exposure, reconciliation and farewell, all came one after another in one summer. This unforgettable youth eventually became the best memory in their hearts.
