Meera was overjoyed when she saw this. She thought that she had actually gotten through to Zack and that he got tempted by her offer.
After all, she always thought that he had been putting up so far with Shreya solely because of the job. And that he was always nice to Shreya because of the position she holds as her employer and as the heir to Sri corp. And now that she had offered him another job far from her, she thought he should be feeling like she had broken him out of the prison or something.
So she continued joyously without even noticing that iciness in his face.
