Lin Wan, who was on a graduation trip, followed the invitation of her best friend Chen Meijia and stepped into Room 3602 of the love apartment deep in a Shanghai alley. The moment she opened the door, the room was full of laughter and laughter - Hu Yifei, a university professor with a black belt in taekwondo, Zhang Wei, a simple and reliable "legal pioneer", Lu Ziqiao, a dedicated "love expert", and Tang Youyou, a talented actor with a high body of drama, a group of roommates with different personalities, built a warm harbor for her with enthusiasm and sincerity.
During the days and nights in Shanghai, they went to the Bund to admire the neon lights, and went to the City God's Temple to taste snacks, building up their friendship while laughing and playing. An unexpected reunion led Lin Wan to meet Lu Zhanbo, her senior whom she had a crush on in high school. Time has not changed their original intentions, and their ignorant feelings have quietly heated up as they get along day and night.
In the living room of Room 3602, the hot pot is steaming with fireworks, the board game table is full of laughter, and there are tender moments hidden in every corner. There is mutual help between roommates, the youthful throbbing like lovers, and the love for youth and life. This is a story about encounter, companionship and growth. Those gentle echoes in the love apartment will eventually become the most precious memories in the years.
