Saeki Kazuma and his girlfriend Izumi Yukari were spending a fun school life surrounded by plenty of friends.

Then one day, Kazuma and Yukari went to the Alpaca Kingdom together.
When Kazuma woke up from his nap on the bus back home, he looked to the side and saw his cute...

"...Wait, whaatttttttttt!!!!"

Yukari, who should've been sitting there, had disappeared,
and in her place was a single fluffy wuffy alpaca, sitting on the bus seat.

"Wh-what's wrong, Kazuma-kun? You suddenly yelled..."

The alpaca looking quizzically at Kazuma had clearly spoken in the same tone that his lover, Yukari had.

And thus began Kazuma's sudden summer with an alpaca.
