Gabriel gets used to... (Adrien having a girlfriend)

Gabriel Agreste...

The man; the myth, the legend; the grumpy old man who wouldn't know love if it kicked him hard and straight up the hiney.

Gabriel had a number of issues in his life, but the worst one goes by the name Marinette Dupain-Cheng; his son's girlfriend and the younger Agreste's self claimed 'love of his life'. In Gabriel's eyes Marinette has a mission, and that mission is to take everything the Agreste's have worked hard for.

One thing was for certain, he wasn't going down without a fight; and if his ship did finally sink he was dragging Marinette down with him.
