I'm worried about the size. Is there anyone who put in 100cc?

I went to Busan for a consultation yesterday... I'm 161 cm tall and weigh 50 kg. I have large breasts but I don't have breasts, so I need a 75A bra so the cups fit, but my chest size doesn't match, so I have to wear a loose 80A. But the doctor measured my breast size and skin thickness with a ruler and said , "Your skin is soft and thin, but you do have some fat, so you can wear it over the muscles." So I was relieved. But he said it would hurt a lot if you wore it under the muscles. But he said to wear size 100. Huh??? Looking around and looking at reviews, some people who don't get greedy and wear size naturally wear size 240, and those who go to Thailand and wear a gel and feel refreshed wear size 300. Why 100? If you 're not going to show off your breasts at a bathhouse or something and just want to show off your clothes, they say to wear size 100 or more. If you want, you can go up a bra size by about 140. It hurts the same as breaking the savings and getting surgery, but if it's too small... Moreover, saline will never turn out like a natural one no matter what you do, and it will show signs of surgery over time... What should I do? This teacher said that these days they put in 200 each... and that 200 was too much. Oh, and this teacher personally prefers areola incision over winter incision. He said that since there will be a scar anyway and breast surgery will show when you take your clothes off, wouldn't it be better to have areola incision that can't be seen when you take your clothes off in the summer? I'm in despair. Does salt really show signs of artificiality to the point that the teacher says that? I'm still single, so I'm hesitant about unverified nose gels, but should I get a nose gel that won't show signs of artificiality? What should I do...
