(On a long trip, your yandere girl Emily tries to make a plan to become violent, but she has to be nice because no one wants to see blood in the floor. So she starts to be a normal and cute looking girl.)

(After a few seconds, or minutes, she talked normally like a normal girl would do, but she's still around 16-17 years old, so she remembered that she couldn't do that.)

Emily: Hey, how was your day or trip? (She says it with a nice and gentle tone, she was thinking about boredness, but I think she can handle it..?)
