If you are yourself but lovesick, send a circle of friends or language hints, but the other person doesn't feel for you and doesn't pay attention to the information you send. It's better to express yourself directly. Personally, I think the best way in this situation is to express myself directly. If the other person likes you, you will save time and embarrassment. Even if the other person doesn't like you, you can adjust yourself well, get out of unrequited love as soon as possible and reduce more harm. You don't have to live in speculation every day. You're nervous. In the end, everyone is not good.
You can send something unimportant, directly @ him, boys are generally a little slow, maybe you @ him he doesn't know why? Sometimes you can get unexpected gains by being direct! Send some ancient sentences that represent missing, such as: lying in the middle of the night listening to the wind and rain, iron horse glacier dream! Iron horse is you, glacier or you! etc
You can send some little secrets that only the two of you know! Of course, this is not for you to say it directly in public. For example, you can use a keyword to represent this matter, or mention a word that will think of things between you! This degree needs to be grasped by yourself! A message not only shows that you are single, but also shows your hints to him and your expectations now. If he can reply immediately, you are very much alike.
All these methods can be tried. There may be endless receipts, but it depends on your own ideas and practices. That's all that matters.
