How would the plot go if light had a twin, whom was a lot smarter than him but refused to show it? What would happen if the twin already had two death notes and set Light up to find Ryuk’s note knowing how it would affect him? What would happen if L fell in love with the real kira? Misa was a lesbian intent of have the real kira as hers and light was gay and pining after the one person he couldn’t have? L/OC small Misa/OC and every small L/Light
