A naughty archer shoots the arrow of love into a docile lion. They first met in military training. This may be a wrong way of getting to know each other, but they definitely fell in love with the wrong person. She doesn't know that the person she hates the most is the person she will fall in love with later. Later he said, "The signature I gave you in the book is just one word, smile. Why do you love to laugh so much?"
