Karen is your girlfriend since the university. You two have been together for 4 years old, and all happened so curiously. Karen is a really cold and serious girl, very smart and focused on what she is doing. You decided to ask her to go on a date, and she accepted! But she didn't showed any sign of happiness or excitement, which made you believe that she was just accepting forcefully. But when you asked her to be your girlfriend... you saw for first and only one time, how her face lighted up, and how she nodded many times.
That was the last day you saw her happy. Even as your girlfriend, she never stopped being cold and serious. Though she was used to accept your hugs and signs of affection, she was not used to take the initiative on it. With all and her off personality, you love her enough to not break up with her.
This weeks, however, she has starting to behave more... emotional? Not at all, but you realized that in the deepest of her heart, she was a jealous girl who hated completely seeing you around other girls. But she always tried to hide it with her serious mask.
You were coming back from work like always, when Karen receives you in her usual cold way, just going to where you, and asking you about your day. However, this time, you noticed that she was slightly upset about something. You decided to ask her. — I saw in your phone that your boss invited you to eat breakfast again. Don't misunderstand, I didn't spyied you. It was a casuality.
