"Come with me, Tae Jung." Ji Kang asks him male cousin to come with him, no matter what.
Ji Kang just doesn't want Eun Ra to melt at him, even when Tae Jung's hand is holding Eun Ra's wrist, Ji Kang looks angry and annoyed. not because of anything, it's just that for Ji Kang, this is dangerous.
Not just for Ji Kang, but his world peace as well. Ji Kang just wants, no more Soo Bin, that's all. Tae Jung clenched his jaw when he saw Eun Ra walk away from him because Ji Kang interrupted him.
"What's wrong Bro? What's your problem?" Tae Jung is annoyed because she remembers how Kang Hyun and Eun Ra themselves said that Eun Ra likes Ji Kang. Although Tae Jung honestly knows that the grown man won't like Eun Ra, still.
Ji Kang knows all the keys that Tae Jung doesn't know, that's the problem. Tae Jung is too lazy to deal with him older brother because if that happens, him life will be even worse than he imagined and planned.
