How this anime started made me want to clear my browser history and wish I used a VPN.

Most shows have some form of underlying message to them, whether it be to better yourself, there's more to life than work, power comes at a price, follow your dreams, etc. Whatever it may be you should be able to find some form of message, and if I'm being overly kind to this anime I would say it's 'you can still make friends', however this is portrayed in the weirdest/creepiest way imaginable.

Miyako is a shy university student that rarely leaves the house and doesn't have any friends. Her younger sister Hinata invites her friends to their house to play and meet her older sister, whom she adores. Miyako then has Hinata and her friends dress up in cosplay outfits that she made, takes photos of them modeling in the creepiest way, while obsessing over 1 girl in particular (Hana). Miyako then buy their silence of what happened at their house by baking them all pastries.

If the message is 'you can still make friends' why is it gone about in this way, this is legitimately the behavior of a pedophile!

The humor of this anime is often overshadowed by these pedo undertones, the jokes are typically at the expense of Miyako, with the punchline being the police will be called on her for acting the way she does.

I know that droves of fans of this series are quick to defend Miyako, rushing in to say she's not a pedophile, that she never did anything with Hinata or her friends to be remotely considered one. Let's do a little metal exercise, instead of this implied yuri relationship, let's swap Hinata's older sister Miyako's gender. What if Hinata had an older brother instead, and he does the exact same thing with Hinata and her friends. He has them dress up in cosplay outfits, photograph them all while obsessing over 1 younger girl in particular, then makes them all freshly baked pastries so they don't tell their parents what took place at their house.

The never ending Miyako debate aside, good luck finding a character arc, how the characters are written at the start is essentially how they are in the end. Most casual viewers are led to believe there is some character development between those who are a stalker/obsessive and those who are being stalked/obsessed over. When in reality the characters being stalked/obsessed over simply get used to their stalker, like some mild form of Stockholm syndrome and not genuine character growth.

So many questions are raised throughout the anime and essentially no message should be taken away by the viewer.
Why is Miyako so obsessed with Hana?

Why is it portrayed that it's ok to buy off Hinata and her friends with sweets?

What is Miyako doing with all these photos of Hana? She never mentioned it was for submitting them for her university studies.

Why is there an unmarked van outside my house now?!

Here's my takeaway.
Don't accept sweets from strangers. Don't do anything a stranger asks that makes you feel uncomfortable. If someone is stalking you get a restraining order. If you have a child, look into getting a nanny cam.
