Well, lahat naman tayo may experiences of secretly loving someone. Kaso, we wasn't able to let them know what we feel for them kasi we don't have the courage. Some were shy, and some are afraid of rejection. Then, hindi natin alam, the feeling is mutual pala. Nag-aantayan lang pala kayo.
As my own experience, I got this situation when a friend of mine told me that he likes me. I really like him too, kaso, I was so afraid to tell him. Until he get tired of waiting & found someone who has courage to tell him that she loves him. Nakakapanghinayang! Kaso, ganun talaga ang buhay. But I still believe that if the two of you are meant for each other, in the end kayo pa rin.
