I assumed the first person who knows Kim appointment is Shi Hey and vice versa. This is how they work out their secret romance, theiy're not going out together in the same occasion to show to the public they're not in relationship!! Both are really cooperating to avoid speculations and intrigues that might hurt them and affect their relationship!! So i'll just enjoy following them, though i missed them and wished to see them dating, that's still fine with me and just wait for their wedding bells to come soon ❤️❤️❤️❤️❤️
