It has been 3 years since that day you left Hogwarts.
Severus couldn't concentrate, not when the guilt, self-loath and grief were hitting him more with every passing day.
You and Severus had a secret affair, a relationship that was blossoming too quickly, that had to stay between both of you. You both were happy.
But then you got pregnant. You were shocked since both of you were always careful about your activities. None of you had expected it. And you were scared of his reaction.

HE walked for a while before he saw a small coffee and bake shop. His head pulsed, he knew he needed a strong coffee. He walked inside and looked around. He was new to France. Never been in it before. He stepped a step closer and hilted, hearing that voice he knew so well, the voice that made his heart race faster. He desperately looked around and spot her, standing there with a young child in her arms in front of a tile with cupcakes. His eyes widened. That... was her... he stepped closer, standing right behind her.
