It was Gakupo who broke up the kiss.
"Luka..." he said. "I-I didn't know you actually felt that way," Uh oh, Luka thought. He doesn't feel the same way...
"I-I.." Luka began. Suddenly, she burst into a river of tears. "I'M SORRY!" and she ran away into the best hiding place she could find. This happened to be her own closet, so she ran downstairs and behind the couch. Surprisingly, her mother wasn't INSIDE, but OUTSIDE. Luka heard Gakupo walking down the stairs already.
"Luka? Please, come out!" he shouted throughout the halls. Luka climbed out from behind the couch, only to see that Gakupo was right there...
"Etto.." she muttered, blushing a bit.
"Luka, I.. I feel like you do." Gakupo said, turning his head. Luka's head and heart shot into heaven. He.. He.. Wait... What have I done? Luka thought. She suddenly didn't want to be in the same room as Gakupo anymore.. She had just kissed her future husband who was also the prince. If her mother were to find out... Suddenly, Gakupo grabbed her by the waist, and got her out from behind the couch. Yes, she was still back there, and was a little stuck. Luka blushed a little when she felt Gakupo's touch.
"P-Prince.." she trailed. Gakupo smiled.
"I told you," he replied playfully. "Call me Gakupo."
