"I want ice cream."

"No."

"I want crepes."

"No."

"I want cake."

"For the last time, no! The last time I treated you to dessert, you practically emptied out my entire wallet."

"But I'm hungry..."

Zanya clenched his teeth, begging for God to grant him patience as he dealt with the ever difficult Kurai.

Gods, why did he even decide to go and study with this emotionally constipated robot.

"Use your own money then!" Zanya exclaimed.

"My wallet only has 100 yen... It's not enough to even buy a drink."

The indigo haired boy felt a stab of pity but ignored it. For the sake of his pocket money, he would ignore the begging from the companion next to him.

"Well, it's your fault that you didn't save up enough. I bet you spent all your money on sweets, that's why you don't have any money now!"

" I get 2000 yen a week, rent from the motel including meals cost 1000 per week. Plus, the journey to school and back cost 100 yen in total everyday."

Zanya stared open mouthed at Kurai. "But... That means you only have 500 yen left..."

"Precisely. Zanya, close your mouth, you'll catch flies. "

Zanya blinked and closed his slacked jaw. " Fine. I'll let you buy one small size ice cream cone. But only this once."

Bonus :

"DAMMIT KURAI, MY WALLET CAN'T SURVIVE YOUR SWEETOOTH! "

Kurai held gigantic vanilla ice cream cone and ignored him completely, linking contently on her ice cold treat.
