As a present from the literature club members, Andou receives an original game featuring him as the main character. He was impressed by the quality of it. However, it was actually made primarily by Sayumi, so Sayumi took off to recover from the fatigue. The club decides to send Andou as their representative to visit her.
That's why I decided to follow you.

Et que c’était pour ça

Per questo decisi di seguirti.
Foi por isso que decidi
