Having a crush on someone means that when you suddenly see him or her walking towards you, you will feel an unexpected electric shock like being struck by lightning. Although you will act very calm and composed, as if you have never met before, and walk past him with an aloof and indifferent face, it is difficult to conceal the nervousness, panic, shyness and uneasiness in your heart. I'm always paying attention to you, in any way you know or don't know.
Intention: If you like it, go for it and don't have any regrets.
