which common area of conflict does this situation represent?

Management of money

Explanation:

Money management consists of tracking, forecasting and managing costs. That is, through the referencing of money a person's costs are calculated, the expenses that he will have to cut and what he can or cannot do with his money. An example of this can be seen in the question above, where Sora and Nikita will have to cut some unnecessary expenses because their expenses have increased.

Personal money management must be taken seriously, just like in companies. Especially at the time of the current economy. Knowing how much and what the money is invested in is essential for planning financially and not getting into trouble. Having a spreadsheet in which the outflows of money are noted, and even with what that money was spent, contributes a lot to this control.
