Manifesting someone you're interested in, especially when they're far away and you don't have direct contact, is absolutely possible!! So, don't worry at all...
Start by focusing on yourself and your own personal growth. The more you work on becoming the best version of yourself, the more attractive and magnetic you'll become. And, this will manifest this person by default without you even having to lift a finger!
Try to also imagine a scenario where you and this person are happily together, whether it's a romantic date, a fun conversation, or just spending quality time together. Let yourself lovingly daydream on this in the most enjoyable way possible.
Keep an optimistic mindset about love in general and trust that the Universe has brilliant ways to orchestrate this. You don't need to know exactly how it will happen; just believe that it will.
