Yejin has already fallen for Kai but he isn't interested in having a girlfriend, despite his flirtatious nature around Yejin. When he can no longer deny his feelings, he makes a promise with her. The only question is who can keep this promise and who can't. This story is kind of personal in a way so it was pretty difficult to write. It's not a tragedy or anything but it's based on a frustrating boy in my life and I just needed some way to vent. It's only a few chapters long (originally a one-shot) but I hope you will like it. And yes, I am a big EXO fan. Kai and Kris are my biases hehehe but Luhan and Baekhyun are close behind.
