Youngji stated that she wants to have four kids.
Youngji is so hot that she could probably make her man jizz inside of her four times in 30 seconds. Unfortunately for her, it's highly unlikely that would result in four kids for her.
I think this is foreshadowing something ominous for Youngji's career. With Kara's breakup, does Youngji really trust that DSP will help her going forward? At best, Youngji will be able to go on various variety shows to make her money, and at worse she would be added to April.
