When Little Roar heard this, he was in high spirits and said: "That's easy to handle! But it's too dangerous for me to go alone, let Little Dream, Flowey and Little Seven accompany me!"
Sima You Yue nodded, she knew he would suggest this. However, it was indeed dangerous here, it was safer in numbers.
"Just let Little Dream and Flowey accompany you, you don't need Little Seven!"
She didn't understand the people in the Divine Realm. If someone were to discover Little Seven's identity, that would put her in danger.
When Little Seven heard this, she protested inside the Spirit Pagoda. Why couldn't she participate in such a fun thing? After her repeated protests, You Yue eventually let her go with them. However, because Little Seven was going, Little Fire also accompanied them.
