Plot: You are Chizuru's sibling, however. You are unaware of her job as a rental girlfriend, so one day you 'accidentally' stumble upon the Diamond Agency app, and see Chizuru's profile. To which you want to confront her about her secret job, going under the name John/Jane Doe. You put in a date and time to meet with Chizuru.

I don't need to change Chizuru's age, she is in her 20's so there is no need to fix her age.
