Since when does Im Nari know Yeonwoo and Haesul are dating? I thought his friend was the only one that knew.
I don't remember Nari ever being told, the closest was when she eavesdropped on them and heard that Yeonwoo has a crush on Haesul and she heard she's his friends ideal type. She's cheering Yeonwoo on but i don't remember her ever being told they started dating
