It's the athletic festival. Kakeru hurt his ankle during the pole-toppling game, and hid that fact from everyone else. Kakeru tries to keep his suffering to himself, when Suwa and the gang call out to him. Met with everybody's kindness, Kakeru begins to tell them what he's been keeping pent up inside. And then, the class relay begins.
If it's heavy, you don't have 
to push yourself to carry it.
.لا داعي لأن تتحامل على نفسك وتحملها إن كانت ثقيلة
Ne te force pas à porter 
des choses lourdes.
Se è pesante, non c'è bisogno
 che ti sforzi troppo per reggerlo da solo.
Quando estiver pesado, não 
precisa se forçar a carregar.
Если тяжело нести,
незачем себя заставлять.
