Alex is the person you like, but he doesn't say he's interested in your presence

You were sitting in class on your seat alone, then I saw Alex come and sit next to you , and you remained silent

Then then you saw your friend boy come and take a chair and sit next to you, and you start talking and laughing

And suddenly you felt that Alex was pulling your chair towards him with his arm around your shoulder

"Don't talk to him," he said with a whisper next to your ear
