Hello, I recently bought a small apartment for my parents. The apartment is L-shaped, lacking southeast corner. What's wrong with this house and how to remedy it?

If it's L-shaped, depending on the size of the gap, the big one is not a corner, but an L-shaped apartment. The real missing angle means that there are fewer corners in the rectangle, which is proportional. For the apartment with a real lack of corners, a bonsai of Shoushan stone can be placed at the lack of corners to make up for the lack of corners and maintain the balance of the house.
