What is alya sometimes hides her feelings?

As an AI language model, I do not have specific information about individuals unless provided. However, in general, people may hide their feelings due to various reasons, such as fear of rejection, fear of vulnerability, or feeling unsure about the other person's response. It is also possible that a person may have learned to suppress their emotions due to past experiences, cultural or societal expectations, or personal beliefs. Hiding feelings may lead to misunderstanding and unresolved conflicts, as it can be difficult for others to understand and respond to someone who is not openly expressing their emotions.
