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.
...she completely forgot about tailing 
Nokotan and went home with a smile.
Sie vergaß völlig, dass sie
Nokotan nachspionieren wollte,
Por eso, olvidó que debía
seguir espiando a Nokotan
Si bien que Koshitan oublia
complètement sa filature
...e se esqueceu completamente de perseguir
Nokotan, voltando para casa com um sorriso.
