Brother, you don't want your sister to go crazy, do you?

On that day, my brother knelt on the ground and begged me to save his crush for ten years
As a doctor, how can I just sit idly by.
pulse, massage, injection, guidance
And senior brother knelt outside the door, obviously I met her first, why...? !
"Senior Brother, this is all necessary, you don't want Senior Sister to go mad, do you?"
The senior sister recovered from her illness, and the senior brother mustered up the courage to confess to the senior sister, but...
"Senior Brother, this is what Senior Sister herself wants to confess to me!"
At this moment, the senior brother's eyes lost their light.
But the senior sister lay beside my ear: "Junior Brother, Senior Sister's body seems to be a little uncomfortable, please show me again♡"
