Xia Jingjing and Gu Yu are childhood sweethearts. The two families live next to each other and have a deep friendship. In her childhood, Xia Jingjing was lost on the streets of Jiang City and was rescued by a strange brother who handed her ice powder. This warmth was deep in her heart. Many years later, Gu Yu's family moved to Jiang City due to changes in his father Gu Gang's business, and the two separated.
Xia Jingjing was admitted to the University of Science and Technology, and unexpectedly met the peak person who ran the campus express delivery station - he was the "ice fan brother" back then, and he was also the half-brother Gu Yu had never met. Gao Feng was estranged from the Gu family due to his mother's early death and his family background, but he was attracted by Xia Jingjing's warmth while getting along with her. When Gu Yu broke the relationship between the three, Gao Feng deliberately avoided emotions due to family shadow. Although Xia Jingjing was disappointed, she could not hide her heartbeat.
At the same time, Xia Jingjing and her roommates are experiencing the pain of youth: her best friend Zhang Xiaohong gave up her future for love, Jiang Xiaoya encountered prejudice and self-awakening under the "goddess halo", and Zhang Yu built a wall with reason but could not stop Gu Yu's persistent pursuit. Finally, at the playground on a winter night, Gao Feng broke through his worries and bravely confessed his love, using a "black friend" figure that symbolized his love. Xia Jingjing also responded with a kiss, and the two hearts embraced each other tightly across the family barrier.
Intention: Face the blows from life and never give up embracing the power of love.
