Reborn and Shrunk: The Icy School Beauty Is My Caretaker

Low-budget rebirth + an artificially stupid System + one female lead + campus belle + a microscopic world of shrunken people + 1v1

System: Want to become normal again? Then make the aloof campus belle Su Xiaowan fall in love with you completely.

Xiao Dugui: Are you even speaking human language? What normal woman would fall in love with someone smaller than an ant?

After being reborn, Xiao Dugui discovers he's become a tiny person, just 1.8 millimeters tall, trapped in the skirt of the girl he's always loved from afar.

Cookie crumbs become his lifeline, mosquitoes become his helicopters, and ants become his bodyguards. But after Su Xiaowan discovers him, she locks him in a glass jar and keeps him as her personal pet.

How can a tiny pet win over an aloof campus belle? There's not enough room in this blurb to tell you, so read the story for all the exciting details.
