Kira x Hisagi
Night
Kira, Hisagi knew, came into his own at night, as if the responsibilities and worries that set his forehead into frown lines sank away under the horizon of his subconscious with the sun. He laughed loudly, he spoke brightly, his eyes never strayed into shadowy reflection and the only lines on his face were the small creases in the corners of his mouth as he smiled.
Shuuhei had fallen for him in the night time.
It was the way Izuru had turned to him, his face barely lit by the dim light, and had kissed him, rather than the other way around, fiercely and passionately and expressing a thousand thoughts of relief and gratitude and love and dependence all at once, and the way he had smiled afterwards, at the dazed look of happiness in Shuuhei's eyes, and taken him by his hand, and asked him, sweetly, innocently, if Shuuhei would make him scream now, please.
To which, needless to say, Shuuehi had needed no second invitation.
