あとで

I would be happy if you could properly teach/tell me later.

According to what I later heard from the other party…

I'll have you tell me about it later (at a leisurely pace).

I'll try to ask about it in detail later.

Well then, let's meet again later

I think I’ll look it up later.

Let's have a leisurely chat later.

“Later on, you never know what will be said (to me).”
