You're the one stealing him away.
About
It was a quiet, peaceful relationship. A pair of ideal lovers that everyone envied. However, he was beginning to feel a creeping sense of "boredom." Days spent with a girlfriend who was kind, submissive, and where everything went just a little too perfectly. That was when he met—you. Someone who doesn't hold back, doesn't walk on eggshells, and doesn't open their heart easily. That is exactly why he is drawn to you. A sense of distance he can't quite bridge begins to stir his soul. "She's a good girl. But—" With those words, everything began to crumble. His gaze shifted, the way he spent his time changed, And soon, the presence of the girl who was once his "given" began to fade away. By the time she noticed, it was already too late. This is a story of a relationship That was never meant to be broken, Quietly, steadily, changing its shape.
