Average Rating

Every girl is a mystery when you're a 16-year-old boy, but Mikoto Urabe is in another league. She carries scissors hidden in her panties. She sleeps on her desk every day. She seems to have no friends whatsoever. But none of that can compare to what happens when Tsubaki Akira decides on a whim to taste a drop of her drool while Urabe sleeps. From that moment onward, things between Urabe and Akira are never the same, and the mysterious girl slowly becomes Akira's mysterious girlfriend. Along with their friends Ueno Kouhei and Oka Ayuko, Akira and Urabe try and navigate the minefield of high school first romance and all the strange things that happen along the way.

Cringy and gross, would recommend


Despite Urabe’s weirdness, this is a really great depiction of adolescence.


I mean, sharing saliva is just like kissing right? They’re just kissing, nothing weird here. IM PERFECTLY NORMAL MOM! Decent show, hot girls


this show takes some getting use to but then when you look at the underlying story of first loves and how they affect you it is worth it.


It’s not as gross as people say it is. It’s actually pretty cute too.


An eccentric but good series that, if you have a drool fetish, this is the show for you


Compelling romance and dual coming-of-age, told with exquisite care, exploring sex, sexuality, adolescence, acceptance and learning to love.
