((I'm feeling good today, so i'm going to make as much chapters as i can to make up for the past week until midnight! ))
After a few minutes, Koji ran out screaming.
"My teeth! They burn!." Miku came out running after him.
"I'm sorry! I didn't know that it was acne cream, not toothpaste!"
"Water! I need water!"
"I don't have water, but i have soy sauce." Miku said, panting when she caught up with Koji, who stopped.
"Soy sauce is good! Gimme!"
Miku handed over the sauce and Koji filled up his mouth, then spat it back out.
"It still burns!" Koji moaned.
"Yea yea, I know, it'll wear off soon." Miku said, patting him in the back. "Don't worry, this time I'll check." She held up the toothpaste.
"Hmm. A-C-N-E C-R-E-A-M. Toothpaste! Here we go!" Miku spreaded the acne cream on her toothbrush, then started scrubbing Koji's teeth, making him scream in pain
again. After a few hours of repeating that over and over, the ghosts have gathered, just watching Miku "accidently" misread the acne cream and burn up Koji's mouth.
Soon afterwards, Koji got tired and said, "I'll take care of my teeth next time, just please, sis, let me go." He got on his knees and begged. Miku grinned at him and said,
"yee---no. Aw, i'm just kidding see ya." She gave him a lollipop and patted his head. "now be a good boy now." she stressed the word, "good."
