Character Scenario/Princess Who Never Laughs

On the appointed day, Putra announced her name at the door, and the door opens easily, despite her wish that the request was a mistake.
Putra	"Sorry to distuuurb you!"
I entered the lady's house together with Putra. She seems to be wealthier than I thought, and I regretted that I let her take the job so easily. If something goes wrong, it could be a big deal.
Putra	"You didn't even have to come, Conductor... Gosh I'm not that much of a child, don't babysit me...!"
Putra	"Ah, sorry bout that bother, mother! Now then, I'm going to get your daughter into a fit of laughter hereafter..."
The lady led us deeper into the mansion. Still, despite the vastness of the mansion, it's worrying that there's very little people.
Putra	"Hello there, I'm sorry to disturb you for a moment~!"
Putra	"How are you feeling? I'm going to make you full of energy with my live comedy now~"
No response from behind the bed, which is closed off by a thick laced canopy.
Actually, on the conditions of accepting the commission, the lady made us promise a couple of things: One, never open the canopy; Two, never force a conversation;
Apparently, these are measures to avoid aggravating her daughter's condition, but this must be very difficult for performers. They said they can see her from the other side.
Putra	"Well then, I'll get right to it~ First, the courting dance of the eldest son slime!"
Putra	"Hmm, you seem to have an eye for humour! Now for the courting dance of the second son slime!"
Putra	"And now for the courting dance of the third son sli~me!!"
Sure, rhyming and repetition are some of the essential comedic devices, but in Putra's case, I don't think she's thinking that far ahead...
Putra	"Hah... ghahah... she's a good one. If this doesn't work, guess I'll just have to attack her with my Seaweed Series on a steel plate..."
She seems to have a wide repertoire of gags, as she's usually very loud about them. But more importantly, is that the lady's daughter still wasn't laughing at all.
It must be mentally tough for the performers not knowing how the audience will react. But Putra doesn't give up.
Putra	"Alright, next! ...Oh is it time already? Is the show over for today?"
Putra looked disappointed at the instructions of the lady who entered the room. But she did not seem to have given up at all yet.
