On October 7th, the person in the costume (who she confirmed is a guy) asks her to help him with an experiment on the next day. She notes the costume isn't creepy, just weird. On October 3rd, she notices there was another person next to them who wears a weird costume, and she is unsure if it's a guy or a girl. On October 2nd, she summarizes the day as 'totally uneventful', aside from meeting her senior lab partner, who is her type.
She is very excited to be working on something so important. On October 1st, after graduating from university, she begins working at the Love Lab.
The girl keeps a Lab Journal detailing the events when she joins the lab.
