Yu Nian and He Yuncheng had been together since college. They had a good relationship and got married not long after. Yu Nian unexpectedly learned that He Yuncheng had someone he liked and that he had gone abroad and treated himself as a substitute, and was not sincere towards Nian. Not long after Yu Nian left due to illness, He Yuncheng regretted it after seeing the letter left by Yu Nian.
Intention: I hope that I will cherish the people in front of me, love has no gender, and love boldly.
