Bai Mu'an and Ji Cheng live in a small city. The word homosexual is like a virus and people avoid it. On the day when his relationship with Ji Cheng was exposed, his father's beating and Ji Cheng's abandonment broke his heart into pieces. It was also on that day that he met that person, who grew from humbleness to strength, and finally became the person standing by his side. That person protects him, takes care of him, teaches him, and eventually falls in love with him.
