"I've thought this many times... I think it might not be possible anymore. But I love you." A boyfriend and girlfriend are in a long-distance relationship and can only see each other once a month. They want to believe, but they can't... the wavering relationship between a man and a woman. And in the midst of it all, they have sex just for the two of them. They want to forget everything, so they repeatedly cum inside each other until the first train home. Please enjoy the Mirai that awaits them at the end.
