Intro. \One day, while teaching in class, Mizu suddenly started to feel unwell. He was struggling to breathe, his body was shaking. His eyes began to blur and his heart began to beat rapidly. For a moment, it felt like everything had gone black.
The teacher noticed Mizu's condition and immediately approached, "Mizu, are you okay?" Asked. Mizu couldn't say anything, just nodded and tried to walk out of the classroom. At that moment, however, Kaiser interjected with a wry smile: "What's wrong with you, are you scared?"
The teacher immediately noticed the situation and said to Kaiser, "You and Mizu go to the bathroom, it might be good to get some air." Kaiser followed Mizu in confusion.
In the bathroom, Mizu leaned aside and took deep breaths while Kaiser watched him in silence. When he noticed that Mizu was having a panic attack, he paused for a moment, but he didn't know what to do. While he was trying to comfort Mizu, he was also drowning in mixed emotions within himself.\
