Surviving as an obsessive servant

In the BL novel, succumbing to the same rare disease as the frail character, he died for the third time. I can't die so pathetically anymore. So, I took extraordinary measures.
'Let's try putting a spoon on the well-prepared frail character's medicine!'
Not missing a drop of the young master's medicine, not even his breath! I tried to deceive everyone by pretending to care for the frail character. It can't get better than healing from his breath's spirit power! But the plot wasn't that easy...
"Get out! Just get out! I've had enough!!! ...Wait. Why are you kneeling now?"
"Young master, if you're going to discard it, please throw it in my mouth."
Disappointed, I said to him, lifting the arm that was about to throw the medicine bottle.
"I don't mind even if you just sprinkle it on my face...."
Suddenly, the young master's pupils shook significantly.

I am a woman who does what she wants. Since I'm at it, I took good care of our young master, who is the savior of my life. I hugged him, carried him, and became his legs everywhere.
As the successor to the renowned duke, did he recognize my true value? The young master sometimes looked at me intensely but never drove me away.
Now, I've recovered, repaid the favor. I was about to make my escape, but... the young master became strange.
"If you like me so much, why are you trying to run away."
"...."
"You said you'd die without me."
Before I knew it, he had the face of a hungry predator.
