In life, there will always be one thing or another that disrupts your original plan and ends up taking another path, leaving you mostly filled with emotion and regret.
Maybe we originally had such a relative around us, but she passed away due to various accidents. If she was still here, would the ending be different?
When the dream you want to achieve is wiped out by the cruel reality before it can be realized, maybe it is just a little bit short, you can continue to work hard to chase your dream.
That little bit may be money, it may be ability, it may be information, it may be a letter of recommendation, or it may be an unintentional word of encouragement from others.
In short, just a little bit of fate makes you and your dream face each other across the mountain, becoming parallel lines that will never intersect.
