Ghoul: What Should I Do If My Colleague Turns into a Monster?

He is still a growth-oriented protagonist, but this time there is no time travel, and there is no system. The logic is rigorous, the character is not OOC, and the protagonist is from a purely human perspective. --- Thousands of miles away, he grew up in a CCG orphanage. After graduation, she was assigned to District 20 with her best friend Masamichi Takizawa. On her first day in District 20, she opened a coffee shop called "Antique". That was the last door she should have pushed open in her life. She loves to laugh and make trouble, and blushes when someone stares at her. She thought her days would go on like this. Then one day, he disappeared. No one can be seen alive, and no body can be seen dead. The CCG said he "may have been killed in the line of duty". After that, she applied for Kuynx's transformation and was transferred to the QS squad as the squad leader, leading four Kuynx on missions. Qian Zhiyao went from second class to special class, from walking into "Antique" with a smile to never daring to open the door again. --- Note: The previous work "Sister Quan is Ready to Eat Me" is better this time. I read the Fangzhong comics again. This time it's from the perspective of an investigator. Unlike the last protagonist, this one will be smarter.
