One day, Hanzaki Bakuya, a high school boy suffering from insomnia, meets a younger girl named Kobirimaki Kimitori, who is eating a delicious cup of yakisoba noodles in a park late at night. Then she says she will help Bakuya get a good night's sleep, and suddenly proposes that he come to her house! "It's just like senpai to walk into a girl's room and suddenly take a smell of her scent." "…Senpai. You're staring too much at my boobs." And then, Kimitori-chan, who teases Bakuya whenever she gets the chance, whispers naughty words in his ear and spends a long night sleeping with him...! (MTL)
