Can you remove it by putting a cotton swab in saline solution?
When I asked the director if I should wash my nose, he told me never to do it. ㅠ He said that boogers become soft when water gets into your nose after washing your face, so I should gently remove them with a cotton swab.
But even with a cotton swab, it doesn't work. ㅠㅠㅠㅠ
