Ke Peng and Gu Jingyi had known each other since university.
After graduation, Gu Jingyi landed a decent job, while Ke Peng always had very unstable work, so for the three years after graduation, most of their living expenses were covered by Gu Jingyi.
However, at the time, their relationship was very good, so neither of them really minded these things.
To Ke Peng, Gu Jingyi was truly sincere, which was one of the reasons he felt guilty day and night afterward.
Another important reason was that, when Gu Jingyi was diagnosed with cancer, because Western medicine had no cure, Ke Peng sought traditional Chinese medicine treatments. For a long time, they only used traditional Chinese medicine, and as a result, they missed the best window for treatment.
Even though Ke Peng did everything in his power to help Gu Jingyi afterward.
That's why Ke Peng has always felt an immense sense of guilt.
