Congratulations,
@Azure_Fog , for writing a chapter of over 9000 words. Reading it, it's evident how much fun you had writing it and bringing your fantasies to life. The most commendable thing is that you made an effort to include almost all the characters, giving each one their moment in the spotlight. Congratulations, only you could have achieved this.
Despite everything, Matcha fared quite well, especially if we consider what happened to En-chan.
Undoubtedly, you are the Villain of this story.
Just never show that chapter to any doctor. Maintain your anonymity. I also recommend an FBI-proof VPN.
