I’ve just created an Instagram account where I posted my piano covers and my guy friend followed my account. Few days later two of his male friends?

What does it mean? The next few days, two of his male Instagram followers who are also his workplace friends followed my piano account as well. Why would guys follow my piano account. There’s nothing special to it and I only had 11 followers at the time when they followed me.
