Suzy was the first person who showed Chris the true mirror since they got married. She never sugarcoated reality. Never ever mixed her purpose and relayed as it was. She never shied away from the fact of marrying him and clearly stated that she wouldn't divorce him.
Even at Chris' down time when he was supposed to be left alone like an orphan, where his own grandfather, who claimed to love him the most, didn't stand for him.
Suzy hadn't abandoned and supported him.
At the moment he was like a lost pup who found his family.
'You have shattered and crumbled all the walls inside me. I don't possess a heart to harm you, Suzy!'
Chris thought and discarded his revenge plan, because Suzy's efforts and pure intentions overpowered his negative emotions.
He vowed sincerely in his heart, 'I will try my best to match you, Suzy. I promise to protect you and stay by your side forever.'
