In a few days, a very important and close friend of mine will have a birthday, but I'm at a loss whether to send her a message or say hello.

Don't give up if you still want to chase. I once chased a girl, almost like you, and felt very humble, but that girl is just an ordinary friend now, not even an ordinary friend, because she found herself wrong, and she avoided me and my object, but you still have to see for yourself whether you want to. If you think it's possible, or you still like her, you can send it! Don't do what you regret now, because no matter what you do today, you will regret it later. Actually, it's not necessary. It's not necessary. Just to make you happy now.
