An unexpected romantic spark has been detected between actor Im Won-hee and Baby V.O.X member Lee Hee-jin.

On the upcoming episode of SBS's 'My Little Old Boy,' airing this Sunday, June 28, the two stars at the center of these "pink-hued" dating rumors will embark on a special driving lesson together.

During a recent recording, Im Won-hee met with his close friend Jung Suk-yong and piqued everyone's curiosity by revealing he had invited a special guest to his home. "I promised to give her a driving lesson," he shared. The studio was immediately abuzz when it was revealed that Im Won-hee was also the one who initiated the invitation to grab drinks together.

The guest was none other than Baby V.O.X member Lee Hee-jin. This unexpected meeting sent shockwaves through the studio, especially when special MC and fellow Baby V.O.X member Yoon Eun-hye added fuel to the fire. "I actually heard about the romantic vibes between the two at the hair salon," Yoon teased.

Im Won-hee went all out for his guest, preparing a pasta dish and even attempting a unique plating style using wine glasses. While the "Mom Avengers" in the studio were touched by his sweet efforts, they couldn't help but burst into laughter at the surprisingly shocking visual result of his culinary creation.

As the atmosphere warmed up, Im Won-hee mustered the courage to pull off a surprise "forehead tap" flirtation, sending the studio into a frenzy once again. With the cast reacting that they had "never seen this side of Im Won-hee before," viewers are highly anticipating how Lee Hee-jin responded to his sudden move.

Meanwhile, Lee Hee-jin opened up about the painful memories of her past relationships. Admitting that she has a weakness for "bad boys," she confessed, "I've been terrified of dating men." Revealing that her last relationship was in her early 30s, she shocked everyone by sharing that a former boyfriend had not only cheated and stolen from her, but had even held her captive.

What new conversations and emotions will unfold between the two as they begin their driving lesson inside the cramped car? The meeting between Im Won-hee and Lee Hee-jin, promising a unique blend of excitement and tension, will be revealed on 'My Little Old Boy,' airing this Sunday, June 28, at 9 PM KST.
