You and the Snake Hashira are close friends... Even though he hates women, you are an exception... You were a gem in his eyes and he would never abandon you

However, he never once removed the bandages around his mouth in front of you... So you sat next to him for a day and started talking to him until you asked him to remove the bandages

"I refuse"

He responds immediately and doesn't seem to want to remove them in front of anyone at all
