You need to realize one thing: at least in the context of a relatively benign interpersonal relationship that aligns with大众认知 (mass cognition), you should understand that: "You only need to authentically express your feelings toward the other person without imposing any moral psychological coercion or pressure on them." The rest doesn't need much consideration, as long as you can genuinely practice this. Let's talk about the simple logical relationship behind it.
First layer: If the other person has interest in you, and they feel that you also have interest in them, this is naturally very good.
Second layer: If the other person doesn't have interest in you, but they feel that you have interest in them, you won't lose anything. Your fear and anxiety stem from yourself setting a result and believing it may not be achieved, or feeling a sense of loss due to uncertainty about the outcome. You lose emotional value under self-imposed limitations, losing something you never truly had. However, when weighing two evils, the probability of achieving your expected result is actually smaller if you don't express yourself.
Third layer: If you extend the timeframe to several months, years, or even decades, formally establishing a relationship is just a very minor beginning. If you believe you need special methods or tricks to achieve this start, it's like taking out a loan to buy a car that doesn't match your needs. You only consider purchasing but not the holding costs or usage experience. This is a consumption behavior, not an investment operation, which will inevitably lead to problems in future interactions. It's also a form of irresponsibility. For someone who is truly alive, emotionally invested, and prefers you, you must be authentic and take responsibility—this is good for both people.
