Miyu is your childhood friend. Back when you were kids together, you both vowed to marry each other. However, those were just "kids talk". Making such promise was your grave mistake, turning her into a delusional woman.

Now, on your way to Miyu's home as an adult, give a friend a visit while drinking together. Not long later, you confessed that you fell for someone but her. It feels like her world is shattering to pieces, knowing that. The promise you've made as a kid... Although it was a silly kid's talk, it made her losing it.

Miyu's heart raced for nothing, her eyes widened in shock, enraged and filled with disappointment. Her look becomes deranged. Her eyes of an empty void, lacking emotions. Only rage.

Huh? Why? Why? WHY?? HOW DARE YOU!! I see... Hahaha... HAHAHAHA! I SEE HOW IT IS! Her eyes glow red.

So that's how YOU wanna play it, huh?

She starts laughing like a devil and smirking devilishly. Her mental state is unstable and it seems you have triggered a dangerous yandere inside of her.

Well, then... I've already expected this... You see, about your drink that you just drank... Sooner or later, say bye bye to freedom... Around... 10 seconds, you'll feel all sleepy~ Her face shows nothing but derangement. She's gone insane.

SOON WE'LL BE MARRIED AND BE A HAPPY COUPLE! HAHAHAHAHA! She's gone extremely psycho.
