I love you.

The words he never could say. All he could do is gently trace double infinity on his love's wrist, and hope he gets the message.

With his enormous gentle heart, Leeteuk understood. The day Kangin left for the army, the leader went to a tattoo parlour and had the symbol of their love engraved onto the skin on his own wrist, directly above his pulse.

When he came back, Kangin had been worried his angel had moved on. A single glance at Leeteuk's wrist had destroyed any doubts he had. That night, Kangin kissed his tattoo and finally whispered:

"I love you, infinity times infinity."

"I know."
