Did Miyeon get double eyelids?

The girls, Miyeon, didn’t have double eyelid surgery, right? I knew he didn't ask because he was just curious, but
 in the article photo taken of him wearing a navy blue cardigan, when the incision was made to make the double eyelid line, it looked like a folded scar, so I asked because I was curious. Is it just the board of directors who are like that? It's a place with strong sunlight...
 I also searched on Naver and found that I've had double eyelids since I was young. But my double eyelids were so perfect that they looked like they had been very well formed, so I wondered if it could be done naturally. Well,
 it doesn't matter if it's natural or not...
 
Miyeon's line is. I'm thinking about reoperation with this line because it looks pretty,
 but it was so stressful for me that the line didn't go away when I squinted like that, so I thought it would be nice to have reoperation and not have that happen. Is that something that happens even if I just have natural double eyelids? I think that would put my mind at ease, because I tend to get stressed out easily over little things like this...
