On an upcoming episode, a younger man delivers bold INFP-flirting, stirring a potential love triangle.

Subin of TOMORROW X TOGETHER is shown learning from a younger man’s “high-level flirting” that makes an older sister notice him. On the November 17 episode of KBS2’s age-gap reality romance “Nuna naega Yeojaya” (Nuna, You’re My Girl), the younger man Kim Sang-hyeon begins to openly express his feelings for Goo Bon-hee.

Previously, Bon-hee had few opportunities to speak with Sang-hyeon, but he asks to talk privately late at night. He asks, “Do you know what INFP flirting is? It’s ‘dressing up and lingering by.’” The hosts Han Hye-jin and Jang Woo-young find the term curious, noting it as a new kind of expression—almost like a confession.

Subin reacts as if realizing something: she explains that the idea of “dressing nicely and lingering” is only part of it, and that learning his flirting method could lead her to wonder if he’s flirting with her, prompting her to become more conscious of his actions moving forward.

Han Hye-jin adds that her flirting usually involves buying expensive drinks and meals, while Hwang Woo-seul-hye chimes in with interest about who his flirting partner might be. After the exchange, Bon-hee remarks that Sang-hyeon feels bold, and she becomes curious about him, with Woo-young suggesting her feelings for Moo-jin may be changing.

The episode on November 17 at 9:50 PM will reveal what changes occur in the triangle between Goo Bon-hee and Kim Moo-jin.
