"I...I think I broke your heart," Justin said. He stammered mournful while looking at her. Every word felt like a stab into his guts.  It wasn't easy for him to admit that. It should have been a wonderful new beginning for both of them. Pointing at her, he bit his shaking lip. There were tears in his eyes. How could he made a mistake like this? "I broke her heart!" Justin took a step back, ripped the name tag off his medical scrubs and watched the heart stop beating on the blood-smeared floor.
