The story begins in college. That year was the best time, when Gu Xin met Xi Chu...
Gu Xin: "Xi Chu, you know, before I met you, I really thought that I would go further and further among the singles... Fortunately, you are here... Fortunately, even if I am lonely, I will not fall in love casually. Fortunately, I met you..."
Xi Chuxiao: "Fortunately, you, a hedgehog, can endure loneliness. Fortunately, I found you, and you gave me another shining star in my world."
Five years later
Gu Xin: "Xi Chu... Well... Long time no see..."
Xi Chu: "Gu Xin, do you know how I have felt your so-called loneliness during your long period of time..."
The story may not go so smoothly, but as long as you are still waiting for me in the end and your original intention remains unchanged, then we will love each other forever in the future and never be alone again.
