This song is beautiful and relatable. I love how the protagonist continues to ask what would happen if "I came to love humanity in the end." They talk about how this world absolutely depresses them and they need some sort of savior. Thus they turn to their doctor for medicine. But even as the medicine begins to work, the world continues to get worse until they can't take it anymore. It reminds me of life in 2020 (notwithstanding the mask on Miku) where I started to hate the world more and more and feel hopeless about it. Additionally, the tempo, drum patterns, key and chord changes and tuning is excellent. I hope Rokuro is okay so he can write more amazing music like this.
