Heaven Is Still Far Away(2016)

Yuzo and Mitsuki live together in Yuzo's small apartment, their constant companionship tender and indifferent in turn. Then Yuzo receives a call from Satsuki, a documentarian resolved to make a film about a now-distant family tragedy, and the three meet, to search for some way to account for their relationship with one another, the memories they share, and those they've kept to themselves.
