Kristen calmed down after I stopped her from confronting Cerise in the cafeteria. I prompted her to confront Cerise outside when they were alone or online.
Since Cerise was weak-willed, then I assured Kristen that she wouldn't tell anyone, "Don't worry about Cerise. She might be a snake, but she's still weak-willed nonetheless," I said.
"True," Kristen nodded. She stared at me with her scrutinizing gaze and asked, "You seem to know Cerise well enough."
I shrugged nonchalantly, "I just know what kind of girl she is. When I talked to you for the first time, I just knew that Cerise was lying the whole time. She keeps telling me that you look kind outside, but you're actually a devil inside."
"And you don't believe her, right?"
"Of course not! Where was she when Jessica attacked me?" I tried to convince Kristen that I was by her side. Not that I wouldn't do the same with Cerise later, it was just part of the game until I get that secret.
