Ren Zai Wan Hua Jing: the Male Protagonist Who Is a Passerby at the Beginning

What is the introduction? The author is too cautious than the dog! What? The cover is the introduction. How about the style? Don't ask, just ask, it's a sweet love story, in the style of a Japanese comic with a single heroine. What else is love? If becoming a scumbag is definitely the system's fault, I will definitely support the single female protagonist to the end, and then firmly hold the votes of the investors in my hands. (Light novel + Japanese manga + daily style)
