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.
laughing like I don't have a care in the world?
أن أضحك بلا أسى؟...
wenn ich einfach so
lache, als ob nichts wäre?
de rire comme si de rien n’était ?
...ridere come se non fosse successo nulla?
eu continuar sorrindo, como 
se nada tivesse acontecido?
могу смеяться, будто мне всё равно?
