Koshitan no longer wants to be driven crazy by Nokotan and decides to spy on her to find her weakness. This leads her to the zoo, where she observes Nokotan at work.
Didja think that was a love letter? 
Made your heart skip a beat, did it?
Du warst bestimmt aufgeregt,
weil es wie ein Liebesbrief aussah.
Creíste que era una carta de amor
y se te aceleró el corazón, ¿no?
Ton cœur a battu la chamade
en croyant à une lettre d’amour ?
Achou que era uma carta de amor?
Seu coração pulou um pouquinho, né?
