I asked a lot about the functional aspects, and they explained everything in detail. If you're going to get double eyelid surgery, they recommend a natural in-line style. It seems like they pursue naturalness. Even a slightly higher line on my eyes feels ridiculously 부담스러운, so I understand.
What I like most is that when I said I don't necessarily want double eyelids, but want to improve my overall impression, they recommended a forehead lift even though the hospital doesn't actually perform forehead lifts. And I had only thought my forehead was sunken, but they analyzed that it wasn't that at all, and that the problem was a mismatch between the brow bone and the eyebrows, causing heavy eyelids and difficulty opening my eyes. That was what I liked most.
They seem to assess things bluntly and realistically and then present a solution, which I liked. Recommended if you want a natural look.
+After looking around everywhere, edit: I do understand why they recommended a forehead lift, but still, actively recommending a forehead lift at my age felt a bit concerning.
