Kyung-Soo had Nivritti in his arms and was kissing her with all the love he could muster. How dare she decide to leave him, the love of her life? No matter how much she would deny, her heart knew how much she loved Kyung-Soo. Just the thought of going away from him broke her heart. But she decided to go away to protect him.
And here was Kyung-Soo doing all he could to stop her. He raced his car to get her away from the airport. He would rush after her to India if the need arose but luckily they spotted Nivritti outside the airport, thanks to Young-Chul.
The moment Young-Chul heard the kissing sounds, he started the engine and pressed on the gas pedal. He wanted something to divert his ears from the sounds inside. He didn't want to hear them kissing or doing something else. It was their private moment and they needed privacy.
