2021 Black and White Anime Girl Avatar, High Cold Temperament, Full of Wilderness, But I'm also Clean

You are my best friend, and I am willing to tolerate everything about you. I know you love being alone, and I will take care of my emotions. It won't make you feel difficult, but you also need to play with me for a while. I only have you. I treat you as my best friend, and I thought you also treat me as the best of us. And all the things between us I thought were already my best friends, but suddenly one day I realized that I am nothing in your heart.
