Why Did I, a Onee-san Enthusiast, Fall for Tiny You?

During the spring break after middle school, Sky Tochika rescues a tiny girl getting crushed on a crowded train. He assumes she’s just an elementary schooler, until he enters high school and finds her in his classroom?!

Clocking in at just 140 centimeters and fueled by energy drinks, She may be tiny, but she's an absolute beauty.

Her name is Chito Naruse. Sky considers himself a true-blue lover of tall, older women, so a tiny cutie like Chito should be completely outside his romantic strike zone. However, Chito kicks off a fierce assault with a bold declaration:

"I'm gonna take that obsession of yours and turn it completely upside down!”

A rom-com tug-of-war over tastes between a guy who loves older women and a tiny girl begins!
