Why do boys and girls have sparks, the kind that they have only met once, but they just say hello every day?

Maybe this boy likes girls, and it's more popular to raise sparks now. Maybe he wants to borrow a plan to chat with you. Finally, you are together. If you know a boy, look at your mood. If you want to spark with him, don't. If you don't know this boy, you'd better not trust him easily. You should study hard now. Now we are in an important stage of life, so don't delay your study easily.
