Finally got it

"In this household, we don't burden others just because we took more than we can take. You don't have servants here, so you clean up after yourself. Carry it on your own!"

What nonsense was that? Nina frowned as this was the first time she heard something so absurd. They might not be her servants, but wasn't it only natural for him to carry her things since he was a boy?

"Only our mom can boss us around here!" Yugi added and crossed his arm. "What a princess."

Yuri frowned and approached Nina kindly. "I can help you."

Help wasn't what Nina truly needed, but she wanted them to take it to her room. However, she ended up not saying a word and carried the luggage with great difficulty. The help Yuri told her to give was useless because Nina still did all the work.
