While struggling to make friends after his parents’ divorce, Koyomi Takasaki meets Kazune Takigawa, but apparently, they already have. Kazune reveals that she’s from World Line 85, an alternate universe in which she and Koyomi are lovers. But in a reality where moving between dimensions is natural, could Koyomi be the one from another world?
"It's not fair." That's what

"Não é justo"...
Foi o que ela pareceu dizer.
Мне показалось,
что она сказала «нечестно».
