전 그것을 이해하고 있어요!
Translation: I’m getting it! (Literally, “I’m understanding that!,” which is as close as a literal translation as I can think of.)
No Lang-8 this week (or yet this week), but my Korean friends are more than willing to help in that regard.
One simple mistake on my part. I completely forgot that “to build/expolot” is 개발하다, and not 개발다 (as conjugated here). So close, yet so far!
