For their one year anniversary, Adrien decided that it was high time that he gave Marinette something from the heart. Not that any of his past gifts to her had been superficial, but he felt that this one had to be extra special.
One year was nothing to laugh about, and he wanted to show her, and everyone else, how serious he was about this relationship (as if the time they spent together was not serious enough).
Adrien had come to Tom and Sabine's Bakery countless times, and had met Marinette's parents long before they had even begun dating. Reintroducing himself as her boyfriend, however, was no less nerve wracking as he would have hoped. The older couple was rambunctiously kind and opened their door to him without a second thought. He was, and would remain, forever grateful for their compassion and for having raised a wonderful daughter with that same compassion.
So, when Adrien asked Tom and Sabine to help him bake something, they were more than ecstatic to help out. And by "help out", they meant provide supplies and instructions, and not actually bake at all.
Adrien was completely fine with that. He wanted the gift to come from him, and to represent the work that he was willing to put forth for the love of his life. What he wasn't fine with, was his inability to do anything in the kitchen. All he wanted to do was bake some simple macrons for his girlfriend, but it was proving much more difficult than he had anticipated.
Flour flew everywhere, and he had gone through more than one batch of batter mix before getting right. He was a mess, and so were the macrons, but at least her parents thought he was sweet.
Tom hovered, wanting desperately to take matters into his own hands. The only thing stopping him was the knowledge of how important it was that Adrien do it on his own, and the fact that his wife would never allow him to ruin such an adorable moment. Speaking of his wife, Sabine had practically taken out a camera, not particularly offering helpful suggestions, but rather commenting on the content of her viewing.
At the end of it all, he came out of the kitchen with flour in places he didn't want flour, a pair of giddy and doting parents, and a dozen pink, mangled, macrons. Sabine slid a box over to Adrien to put his gift in.
"She's going to love them," the woman commented as she assisted in packing the pastries into a gift box. Adrien smiled hopefully at her, and gave both of his girlfriend's parents a hug and thanks before running off to find the intended victim of his distorted baked goods.
