SungMin and KyuHyun are in relationship. They are not the lovey dovey couple but KyuHyun did cared about him (at least on SungMin point of view), and that’s were enough for SungMin. But day by day, a insecurity grew in SungMin’s heart because KyuHyun never said the three magical words.

Yes, an ‘I Love You’ never escaped from KyuHyun lips even for once. And SungMin start to doubt if their feeling indeed are mutual.
