If you find a guy who you have a lot in common with, don't wait for him to ask you to hang out. If you are scared to ask him because you think he doesn't like you, ask anyway. It's scary, but it won't hurt you, and you only stand to gain in the long run. He might also be shy, so he might not be the one to approach, either because he thinks you're out of his league or because he fears you might reject him. . Flirt with him to let him know that you're definitely interested. Lean in during conversations, touch him casually and lightly, and compliment him (do so honestly, people can always tell the difference). . If all else fails and he's still not asking you out on his own, go right ahead and make your move. You don't want him to get away! Have a date in mind (something that will appeal to him) and go straight up and ask. Try to be confident, as most people find this attractive.

How would you rephrase that briefly using Vietnamese?
Đừng sợ khi là người mở lời trước tiên. Tán tỉnh anh ấy. Hẹn hò anh ấy
