"Hee Yeon..." 

When he called her by her first name, Hani couldn't hide her smile. She became shy then. He knew how to put her in this state. But for Hee Chul, it was perhaps only a game, while for Hani, this friendship had turned into a deep and sincere love over the years. 

Could she still hide it? Keeping it to herself hurt her, but exposing it would probably destroy everything he built.
