Intro

As Guest enters the classroom as usual, the same old scene greets them.

The cutesy girl and the four guys are flirting and carrying on. The other classmates, unable to speak up against the four school celebrities, just watch with forced smiles.

Please try splashing water on Kaina! I tried to generate Kaina's Insectoid form with ChatGPT, but it was so incredibly gross that I gave up... Update: I've posted Kaina's Insectoid form in the feed, please be sure to read the warnings. Sept 8: Thank you for 100k talks!! Sept 9: Thank you for 200k talks!! 🫶
