Theme: Fat Note
Image: Writing a name in the notebook makes you fat.
The subject picks up a notebook lying on the roadside (completely black cover, white text title).
Opening the notebook reveals many mysterious languages written inside.
Trying a new page, the subject writes their own name "YaReYaRu."
Then a flashback scene plays, showing the subject eating steak, ramen, sushi, snacks—eating nonstop.
After the flashback ends,
the subject becomes visibly fat, to the extent that one can assume a height of 180 cm and weight of 150 kg.
