One night, Miyako
returned to her apartment as usual after drinking with friends until the last train, only
to find a man she didn't recognize there.

Who is this guy? Why is he in my room?

Miyako was confused, but the man
began crying as soon as he saw her.
Feeling sympathy, Miyako patted him on the head. After

regaining his composure
, the man introduced himself as Nagi. He then explained that he and Miyako lived together and
served her a dish he claimed he had made for her.

No way, no way...

Miyako thought. However,
despite having been drinking and not feeling hungry,
the dish Nagi had prepared looked strangely delicious, and
for some reason, the moment she saw it, she suddenly felt hungry, and
she ended up eating it.

Miyako then
allows Nagi to call her "Mya-chan"...and

from then on, the world seems to break apart and go mad.
