A reminder: jackies love for marco was ideal. She gave him space, and appreciation. She supported him through thick and thin. During his breakdown with star, she tried her best to make him happy. She tried helping him develop talents, and get over his fears, she tried easing him, she tried to give him all the support she could, she tried to never get mad at him no matter what, but at the end of the day, all she wanted was to see him happy. Because his smile was her joy. And that’s love. And when she broke up with him, although you can see her heart broke into two, she was still trying her best to smile. Why? Because no matter how hurt she was, she never wanted marco to feel bad. She wanted and tried to support him no matter what. Even at the cost of her own happiness. When you think about it, its sad. At the end of the day although marcos happiness made jackie happy, when she broke up with him all that was supposedly left in her heart was a bittersweet feeling, of regret, and yet the fear of going back. Because she knows shes doing the right thing. But at the same time, her heart hurts. Since no matter how right what shes doing is, when she broke up with marco, she cut off the emotions THAT HE CAUSED ON HIS OWN, confessing to her to intimately, causing her to fall for him. Jackie is a sad character who was abandoned by the one she loved, and let him go for his own happiness. Shes one of the sweetest characters in the series and deserves a round of applause for her strength and care for those she loves.
