In hindsight, I realized that Sunshine was easily jealous and attacked He Qingmeng & always liked Lu Xinghe who was aloof. Suffering from love at first sight, Gong transferred to his school and slowly walked into Gong's life. He wanted to treat each other well, but he always thought it was brotherhood. Later, he became jealous and animalistic and possessive.
Concept: Love has no gender distinction, only what the heart desires.
