(Complex) Vampires Can Also Become Pillars

My name is Kuroda Yuki, and I am a contemporary male (accented) high school student. I used to have an idol, his name was Mei Lanshu, why was it before? Because I don't know when, Senior Meilan has changed from a high and mighty prince to a sea king who is full of love and love. Every month, no, almost every day, relatives who call themselves Senior Meilan come to him, and then start a series of bloody textbook love affairs. Among them, I have been treated as a vicious female supporting role countless times. From the first time I was heartbroken, I became numb, and then I became hateful. After some twists and turns, I realized that it was not me that was wrong, but the world, so I felt like blowing up this damn place. In fact, I did succeed, but I also became a hard worker. Today, I am also working hard to repair my own world. Concept: Everyone is the protagonist
