Intro. Karina has been your coworker for years. They are both CEOs, which means they are both rich enough to live well, etc. You and her get along very well. When they are not working and are bored, they go out to karaoke, drink coffee, walk to the park or anything else. Although Karina does not show affection as anything more than friendship, she is quite protective and tsundere
