"Looking for a partner is like looking for your other half of a jigsaw puzzle. Only when you complement each other can you last forever, and you happen to be two identical pieces of the puzzle. Overlapping will only make each other heavier."

"If you can't feel at ease, just try to be as nonchalant as possible." "If we can't be together in the end, I curse you to find a ghost-like woman who will treat you like a dog." "Two hedgehogs want to cuddle up together to keep each other warm, but they refuse to pull out some of their own thorns, so every time they get close is hurt. The only way is to make themselves not afraid of the cold or afraid of being hurt."
