I like a company male colleague, sales manager. At the age of 24, he is very busy at work. He doesn't have time to text me. How can I chase him?

Confess, but make it clear that you don't need his immediate reply.

This will give him room to think and improve his position.

Don't harass him to meet him for a few days after confession.

If he really likes you, he will take the initiative to cater to you and get along with you as always.

So you have your own space.

The way to express one's feelings can be by texting, which is very simple, but every word should be on the cutting edge. .
