'Big' featured stars Gong Yoo and Lee Min Jung in a kiss scene.

The latest episode of the KBS 2TV Monday-Tuesday drama that aired on the 18th showed Yoon Jae (played by Gong Yoo) and Da Ran (Lee Min Jung) locked in an intense kiss.

In the episode, Yoon Jae (with Kyung Joon's soul) and Da Ran take part in a scheduled wedding photoshoot. During the outdoor shoot, Da Ran stays depressed, having discovered that Yoon Jae had been preparing to break up with her in the past.

Gil Da Ran tells Yoon Jae/Kyung Joon, "Thank you for the memories. I now have a memory of Yoon Jae with this photo." Disappointed by her attitude, Kyung Joon yells, "I'm the one who held teacher Yoon, but Yoon Jae is the one you're going to remember?"

Afterwards, Yoon Jae gives Da Ran an unexpected kiss; Da Ran in return stares at Yoon Jae with wide-open eyes.

Yoon Jae/Kyung Joon surprises Da Ran by telling her, "This is Kang Kyung Joon's first kiss, not Seo Yoon Jae's" and adds, "Now do you see me as Kang Kyung Joon?", foreshadowing an official beginning to their romance.

Meanwhile, the episode also showed Ma Ri (played by Bae Suzy) becoming suspicious after noticing striking similarities between Kyung Joon (played by Shin Won Ho) and Yoon Jae.
