Spoiler I guess. After this they became partners, think business partners. At least they're trying to be on equal footing. SHJ let HYJ change his name on his phone from "my item." Yoojin changed it to "partner" and Hyunjae added "my" so instead of "my item" it became "my partner" Also, after reading the novel I realized that Yoojin is just as much whipped as Hyunjae. I NEED THEM MARRIED

SHJ became more possessive toward his item after this, no? I mean, if he wants to know about the truth, he definitely need Yujin.
