Quartet and Hollow Doll

After my parents died in a car accident, I lost all emotion. Can't laugh, can't cry, can't be angry, can't like anyone. The doctor said that I suffered from "dissociation disorder" and that I would probably never get better in this life. I thought I would spend my life alone like this—— "Brother, you have to eat well today!" My sister-in-law Xiaoxue comes to my house to cook every day. She curses but is never absent. "Kora-kun, I made today's lunch~" My childhood sweetheart, Sakura, always smiles softly, as if she will never get tired. "Hey, Sora-kun, go on a date with me this weekend!" The hot girl Kohaku at the back table didn't mind my indifference at all, and her offensive was so fierce that I couldn't resist it. "Sora Shiratori, you are very interesting. Let me study it." The student council president, Rin-senpai, got close in the name of observation. Wait, why are they all fighting for me? Why am I being torn between four girls? And... Why am I starting to think, this isn't a bad thing? This is the story of a young man who has lost his emotions and is filled with love songs. Perhaps.
