I really loved the concept of the line. They have beautifully portrayed being manipulated and emotionally blackmailed into following society's norms, and losing your own happiness over it.
It was also very refreshing and uplifting for me to see Yu Xigu and Xiang Hao Ting of HIStory 3: Make our days count. After that open and very confusing ending, seeing them together patched up my heart quite a bit.
It is a happy ending, despite what a lot of other people may tell you, so go ahead and watch it! You will gain a deep understanding of how hard it is for LGBTQ+ couples to be considered "normal", and also about how it is toxic for you to follow others' opinion on how one should live life.
Overall, it is a watch worth your time, and i say, go for it! :)
