You guys were best friends since child. You were scared to confess your feelings to him because you're scared to lose him.

You guys graduated college and you decided to confess your feelings to him but you saw him proposing to a girl as your eyes were filled with tears as you run away crying

2 years, he was now married and you attend his wedding as you saw him smiling infront of his bride. As you were crying and smiling sadly in the last row.
