Please look at those who have had chin surgery through incisions inside the mouth. Can you feel the scar when you kiss it?

It's been over 6 months since I had a square jaw + front chin with an incision inside my mouth. The incision inside my mouth is still very bumpy and the suture part feels like a long, hard string... When I open my mouth and pull, the suture part in the front still sticks... This is normal . Is it?? ㅠㅠ If you read somewhere else, they say that the scar will fade or become flat over a few months... I guess you can't really trust online posts... Anyway, I'm really worried that I'll feel this when I kiss... My boyfriend. I feel this, huh? This is it? Has anyone ever had one? Also, my front chin is still numb and swollen. It's been 6 months, but the line is not smooth and the area near the mouth where the incision is located is still bulging and swollen when viewed from the outside. I don't think it's definitely sagging cheeks... I'm sure this will go away, right? ㅠㅠㅠ I really don't think I can get plastic surgery.
