About this pattern

Explanation

ことにする expresses a deliberate decision or commitment. It can show that you have chosen to do something after consideration, often implying a personal resolution. It is common for planned actions or changes in behavior, and can be used for both positive decisions and decisions to stop doing something. The form changes to reflect the action (present/future decision or decision not to do something) and can be used with nouns by linking them with の before ことにする.
