Love Phantom (2017)

A high school boy is dozing on the train when from his chest, something sticks out as if his heart or soul were escaping. This is a kind of game that Japanese boys play, hiding one arm under their shirts and moving it back and forth. It is usually just a simple trick used to surprise someone, but Takata wanted to convert this silly boy’s prank into a more romantic gesture where the high school boy is flirting with another boy sitting next to him, using the tentacle-like appendage protruding from his chest.
