Synopsis: mouth to mouse

"Wanting to forget something that had happened, Hikaru jumps off a building. Right before he hits the ground, a monster in a human shape breaks his fall. The creature's frightful appearance makes Hikaru cower, but as it continues to stay by his side without saying a word, Hikaru starts to question what its motives are... A deeply moving BL that resonates with the heartbreaking feeling of being left behind."
