1. Contact actively. Whether the person you like is a workaholic or a busy man patting his head every day, he always has time to relax. It's always tiring to think a lot of questions every day, and your brain will automatically want to delay when you encounter problems. If he has you in mind, once he is free, he will unconsciously think of you in his mind, and will definitely think of contacting you for the first time, and will not consider anything else. He will share with you his troubles, happy things and various problems in his work and life. Sometimes he will share some interesting things about his past and growing up. In fact, this part is a very private part of the individual and will not be mentioned casually with ordinary friends. He mentioned this to you because he thought you were someone he could trust and took the initiative to talk to you, which showed that he had a good impression on you. Therefore, when the person you like has the above behavior, it is the first signal that he loves you.
2. I propose to send you a gift. The second sign that he likes you is that he will give you a gift on his own initiative. Please pay attention to the word initiative. You didn't hint at him, nor did you ask him to give it to you. It's that he actively thinks about what you lack according to his understanding of you, and then buys it for you unexpectedly. Because this represents the content of your usual chat, whether intentionally or unintentionally, he has always kept it in mind. And from your point of view, carefully analyze what you should lack, and then find the one that suits you best and give it to you. Every detail of thinking and action shows full concern for you, which can be felt from the gift. Instead of telling him directly, or hinting at what you are missing, he doesn't need to know you at all, and he doesn't need to think hard, so even if he gives a gift, he won't be distracted. So, if you receive his surprise and this gift happens to be your favorite, congratulations, he may be in love with you.
After eating delicious food, you will feel that food is the most important thing for your people. No matter who you are, no matter how busy you are, eating is a must every day. When you find someone you like sharing with you that he went to a store with his friends one day and how delicious the food in the store was, and then said "I'll take you next time", he probably has fallen in love with you. Because it shows that when his taste buds are full of delicious food, what he thinks is not how delicious the food is, but that he wants to share it with you.
