Who knows! The brother next door whom I protected since childhood turned out to be a clingy and domineering suitor when he grew up! He remembered her menstrual period and learned to make brown sugar and ginger tea for her; when she worked overtime, he waited downstairs until late at night; he didn't want other boys to approach her, and when he was jealous, he was like an aggrieved and ferocious little wolf dog. From "sister" to "my person", from longing for each other in a long distance to being together day and night, this secret love that spans time is full of exclusive tenderness only for her, so sweet that it is so sweet that I can't stop eating!
