The tiger next door summary: [I touched the sleeping tiger] Ham A-reum, a professional and job seeker. One day, after a series of failed job interviews, she finds herself lying naked with her childhood friend Baek Beom-yeong, the only man she can talk to comfortably. But... "You take responsibility." "What?" "If you saw me naked, it's over. Ham A-reum, you take responsibility for me." The tiger, furrowing its brows fiercely, warns her. But she doesn't even remember what happened... "Baek Beom-yeong, you go lie down on the bed right now." What happens from now on is because of the tiger's wrath, demanding that she remember everything that happened that day.
