"I Know I Love You" is a urban drama directed by Lv Yulai, featuring Zhang Wan Yi, Sun Yi, Yuan Wen Kang, Wu You in the lead roles, with Yin Zhi Xuan, Li Le, Gu Yu Han, Wang Yue Xi, Tian Miao, Ma Dong Yan, Wang Da Yu, and others in supporting roles.

The drama tells the story of Zhao Jin and Xu Nuo as they overcome numerous obstacles and go from acquaintances to lovers, forming a deep bond. Despite his young age, Zhao Jin has experienced a lot. His father is an alcoholic, and his mother passed away early, so he has been single-handedly supporting the family. He also has a younger sister who needs a bone marrow transplant and requires constant care, as a slight negligence could land her in the hospital.

To make a living, Zhao Jin has two jobs. One is as a veterinarian, where he excels, and the other is as a martial arts instructor. It is through his veterinary job that he meets Xu Nuo, his current girlfriend. However, Xu Nuo has been in a ten-year relationship with her boyfriend, Peng Yu An. Xu Nuo has been torn between her feelings, as it is not easy to end a relationship of ten years. She is aware of how much Peng's family has taken care of them over the years, but Xu Nuo insists that they no longer have any romantic feelings.

Once she truly falls in love with Zhao Jin, Xu Nuo no longer hesitates and initiates the breakup, but Zhao Jin refuses to accept it. Zhao Jin is the person she needs, and their compatibility and Zhao's unwavering care make Xu Nuo feel a warmth and determination she hadn't experienced in a long time. She regains her faith and desire for love and decides to be with Zhao Jin.

Zhao Jin also introduces his sister to Xu Nuo, who starts working at Xu Nuo's flower shop. Xu Nuo also encounters a new romantic interest.

Both characters share similar hardships: one has a brain condition, while the other has blood-related issues. The scriptwriter cleverly brings these two individuals together, allowing them to empathize with each other, support one another, and find solace in each other's hearts.

This drama is an adaptation of the Korean drama "Spring Night" and carries a distinct Korean drama flavor. If you enjoy romantic dramas, "I Know I Love You" is definitely worth watching. Zhang Wan Yi and Sun Yi deliver captivating and tender performances that will leave you enchanted, and their acting skills are commendable.
