MC: "There, i finally finished all of those ridiculous assignments of yours."
Her: "Ah, then Nii-san already done smearing the Catgirl's house with catnip, bathing Robot Nee-san in an oil-bath, and traps the Hornetgal in the Seamstress's web?"
MC: "Yes, i already done all of that...
It resulted in some chaotic mess though..."
Her: "My my, i never expected Nii-san to be so capable!

"
MC: "Yeah so, keep your end of the deal now and wear this maid outfit for me."
Her: "Oh, i did promise something like that, do i?"
---: "Well, too bad Nii-san! That was just a lie! Maybe another day, yeah?

"
MC: "What?! You cannot be serious?! That promise is a LIE?!"
---: "You are not going to even at least compensate me for all that trouble?!"
Her: "Hmm, Nii-san did deserve some compensation!"
---: "And fortunately, i just know the perfect reward in mind!

"
---: "Feast your eyes, Nii-san! Have this delicious cake freshly-baked from the oven!"
MC: "..."
---: "...Uhm? ...Where? There's no cake here."
Her: "Oops, forgive me. When i said 'in mind', i meant it literally.

"
MC: "You mean the cake is a LIE too?!"
