i used to try and be sneaky and hint at insta to make him suggestit like "oh you have an insta? what is it ill follow you" but it's too much work honestly i just walk up to him and randomly ask "do you have an insta? lemme follow you" or something and it always works (they always follow back)
Talk to him as you do everyday and the casually say, “hey do you have an Instagram?” hear his response. There’s nothing creepy about exchanging social media information... I am sure we all do it.
Do it for him. Ask to borrow his phone and when you add him on Instagram put your number in his phone. Tell him thanks and that you added something in there for him to check out. He will find it.
