Senpai should be studying for midterms, but he’s hooked on a game. Questions arise about what might happen if he were to flunk. Senpai and Nagatoro play rock-paper-scissors to see who has to carry their bags home.
And they say that what happens 
twice happens a third time, so...
...ويُقال أنّ ما يحدث مرّتين يحدث مرّة ثالثة، لذا
Und was zweimal passiert,
passiert auch ein drittes Mal, also …
No hay dos sin tres.
No hay dos sin tres.
Et jamais deux sans trois,
comme on dit.
E poi dicono che non c'è due senza tre...
E como dizem por aí, "se acontece
duas vezes, acontece três..."
И, как говорится, что бывает дважды,
то бывает трижды...
