Ep 3. Beware Childhood Friends!

Actually, I am... is a Japanese romantic comedy anime series that follows the life of a girl named Asahi Kuromine who tries to keep a big secret from her peers. Asahi has a crush on her classmate, Youko Shiragami, who is actually a vampire. This secret should not be disclosed to anyone, but Asahi accidentally tells his best friend, which leads to a chain of events that puts their lives in danger.

In the third episode of season one, entitled Beware Childhood Friends!, Asahi's childhood friend, Nagisa Aizawa, arrives at their school for an unexpected visit. Nagisa was always Asahi's protector when they were younger, and he's happy to see her again. But as he spends more time with her, he realizes that Nagisa has a problem with lies. Whenever she feels ashamed or embarrassed, she lies to cover it up.

Asahi is afraid that Nagisa will expose his secret about Youko, so he tries to avoid her at all costs. But when she discovers that Asahi is hiding something from her, she becomes more determined to find out what it is. Asahi panics and starts telling lies to cover up his secret, but Nagisa is not fooled. She confronts him and reveals that she knows he's hiding something.

Asahi finally confesses the truth about Youko, and Nagisa is shocked. However, instead of being scared or disgusted, she is fascinated by the revelation. She becomes determined to learn more about vampires and, in particular, Youko. Asahi tries to dissuade her from pursuing this topic, but Nagisa is too stubborn.

Meanwhile, Youko is worried about her secret being revealed, and she asks her vampire mentor, Shiragami-san, for advice. Shiragami-san tells her to erase Nagisa's memories, but Youko is hesitant about this option. She doesn't want to resort to drastic measures to keep her secret hidden.

As the episode progresses, Nagisa becomes more and more curious about Youko and vampires. She starts asking Youko questions, much to Asahi's chagrin. Eventually, Nagisa coaxes Youko into using her vampire powers, and Asahi is forced to intervene to prevent Nagisa from getting hurt.

Beware Childhood Friends! is a hilarious episode filled with lots of awkward and comedic moments. It shows how even the closest childhood friends can have secrets and how those secrets can have unintended consequences. The episode also introduces a new character, Nagisa Aizawa, who adds new dynamics to the storyline. Overall, it's an entertaining episode that leaves viewers eager to see what happens next.
