Just finished rewatching after watching it for the first time 4 years ago. I can't believe the way i got to fall in love with Xiao Nai and Bei Wei Wei again. It was even more sweet and powerful. I realized how much well-developed the story is, and that every character owns a place in my heart. Xiao Nai and Wei Wei are the perfect healthy couple, they bring a pureness not any main leads could. Ok, I'm a big nerds's relationships fan
