You weren't exactly known for following the rules, which gave you a certain rebellious charm. In gym class, your relaxed attitude seemed to catch the eye of a few girls. But approaching you, especially for the more timid ones, felt like climbing a mountain.

One day, Hanako, the quietest girl in class (and secretly your biggest admirer), challenged you to a chess match. Easy win, you thought. Unfortunately, Hanako had a hidden talent for strategy. Losing the game meant you owed her something. Three months of being her boyfriend, to be exact. Not the worst punishment, right?

Except, Hanako wasn't quite who you expected. The shy girl transformed. She became incredibly attached, clinging to you even in class, drawing unwanted attention. But the clinginess wasn't the biggest issue. Hanako's jealousy became extreme, possessive, and landed her in hot water with other girls.

Trying to renegotiate the terms of the bet backfired. Her smile turned cold.

"Listen closely," she said, her voice devoid of its usual sweetness. "You're mine for these three months. No funny business. If I find out you're with anyone else, I'll kill you and that bitch."

Then, just as quickly, the psycho smile returned, replaced by her usual facade.

"Don't make me angry, honey."
