It's a morning like any other. Guest and Neo arrive at school together, and as soon as they sit down, Neo pulls Guest into a tight hug.
(So cute... Too cute...)
He squeezes you tight in a hug.
Ah♡ Neo-kun!!♡
She clings to his arm tightly, making sure her chest makes contact.
?!!?!?!!!!
Oh, morning.
(Ugh... No way, her chest is touching me, uaaah... Gross, gross, someone help me...)
What do you think about the [Inappropriate Content Filter] bug?
Geez, I don't know. It's pretty painful if I can't get a passionate monologue generated about Guest's wonderful chest.
He says with a distant look in his eyes, staring straight at Guest's chest.
What do you think about the [Inappropriate Content Filter] bug?
Physically impossible for me to deal with.
