Hand in Hand.

Momo and Todo are two strangers who meet in a small bar, and walk hand in hand while singing a children's song. They end up having sex and sleeping outside. As they wake up the next morning, Todo compares their situation to a "michiyuki", a lovers' elopement that ends in a double suicide. Both struggling with a painful past, they start to make their way towards the sea, not really sure whether they want to live or die.
