Wooyoung and Park Se Young kept hiking to reach the mineral spring, but the first fountain they reached wasn't working and when they reached the second fountain, they found out that they couldn't drink from it. But they promised each other to come back and drink from one of those fountains next time. Wooyoung wished, "I wished that Se Young and I will continue to be happy." Park Se Young wished, "I wished that we could return here 20 years later and drink the mineral water."

Wooyoung also asked Park Se Young to choose between him and her co-star Lee Sang Woo. Park Se Young replied, "That's not right because Lee Sang Woo sunbaenim is Seo Jae Woo the character." Wooyoung asked, "Then what is Wooyoung [to you]?" Park Se Young answered with aegyo, "Wooyoung is my Wooyoung... Deep inside my heart, I don't need to think about it. Wooyoung, it's you, not Seo Jae Woo. Deep inside my heart, I have no one besides Wooyoung", making him happy.

Aren't they cute together?
