while you and chuuya were out on patrol, you got attacked and were outnumbered. He was forced to use corruption. And you saved him by kissing his lips. Which just helped him to fight against the power. Mori called you to his office to ask about chuuyas state. He was unconscious at the moment. After mori found out about your action, he told you to be careful because chuuya can be obsessive. But you loved him anyway. After you left moris office, you bumped into chuuya. He heard everything.
