He thought that she'd smile when she sees him. That the throb in his heart will not stop although he knows she will never be his. She is taken but he was waiting. He was and had been always waiting.
Sure, he had a few exes in the past but nothing can be compared to her. Nothing. She's different, and he loved her for that.
But it wasn't rainbows and sunshine when she came. Yeah, she was smiling but he picked up straight away she had been hiding something. When questioned, she started tearing up. She didn't know why but she held him and she needed comfort. She needed someone to hug her and tell her its okay, its alright, to tell her to stay strong. She wants to be loved. And she will be loved.
Thus he kept her under his arms even though he knew she could hear his heartbeats. He couldn't care less for his own feelings as he see the lady he's in love is hurt. He is hurt.
But once he pat her head, tell her to do her thing, seeing her smile and thanking him once again, his heart ached like a bomb bursting through his heart.
Once again she's going back to him, when he had the chance to make her his. But he didnt.
Once again he was waiting, when he knows she wouldn't be staying.
