Answer:
There are a couple of things you should do! first, you should become his friend, and be a good friend, too. Don't fl!rt with him when you first meet, or in the first couple of times you guys meet. Ask him things you are genuinely curious to know about him, don't ask generic questions such as " whats your favorite color" or make small talk. Ask him things that relate to him more like what's his full name, or where is he from. If you really are curious to know what his favorite color is, you can ask him, but make sure he knows you are genuinely curious to know, and not just making small talk. After getting to know him better, you have to ask yourself if you are still interested in him in "that" way, or interested at all, even. If the answer is yes, you still have love interest the next thing you should know is if he is single, or likes someone. When you ask him if hes single don't make it weird if he says no, just be chill. If he is single, but has a crush on someone you should ask him who. If he doesn't tell you and you guys are close already, it's probably you. After finding out all these things about him, you should wait about 2 months and then confess to him that you like him (if he has not already confessed to you) and no worries if he rejects you, rejection happens sometimes and it's totally okay. It may not feel like it right away, or even longer away but you will eventually get over him.
