The imouto Raiha Uesugi of the male protagonist Fuutarou Uesugi says 'うそうそ'
(uso uso).

# Questions:

  1. What's the difference?

  2. Also, in particular what does it mean to use 'uso' here? Like, what's the lie? Some people in fact can [live on 1 kidney](https://www.organdonation.nhs.uk/helping-you-to-decide/about-organ-donation/what-can-you-donate/about-kidney-donation/). I actually kinda think they should be reversed: Raiha is joking that Fuutarou should give up a kidney, while the boss is lying that Fuutarou will be forced to pay the for the buffet.

  * **Edit** : Ok Arie says 'then proceeds to explain why the previous statement was actually a lie.' I checked the manga and apparently they do cut out dialogue in the anime adaptation. Here's full remainder of the conversation up to the stomach grumble:

Raiha: (This part is in the anime.)

うそうそ

Raiha: (This part is NOT in the anime.)

成績悪くて困ってるって言ってたよ

でもお兄ちゃんならできるってしんじてる！

Fuutarou: (This part is NOT in the anime.)

ちょっとまって

やるなんて一言も

Raiha: (This part is in the anime.)

これでお腹いっぱい食べられるようになるね！

Ok so how is that an explanation of why the previous statement was a lie?




I think it's about the original context here rather than how the meaning
translates to English.

From the pictures:

In the 1st scene, the character says `うそうそ` (something like: "lying, lying")
then proceeds to explain why the previous statement was actually a lie.

In the 2nd scene, `ばかり` caries the meaning of abundance of something ("nothing
but"), something like: when it comes to you, boss, it's "noting but jokes".
