Lin Meiyue was much more careful compared to Gu Yuan. She treated "Chu Luoxun," who was not related to her by blood, as her own sister. It so happened that the effort 'Chu Luoxun' had put into 'assisting' her was even higher than her own biological sister.
This probably was a juvenile novel, where the whole world was assisting the male protagonist and the heroine.
Whether Lin Meiyue and Gu Yuan would be able to be sure of their relationship without "Chu Luoxun," even the Goddess was not confident about it.
Therefore, Lin Meiyue brought 'Chu Luoxun' some comforting goods; they were all her favorite sweets, cakes, chocolate, etc. Then, 'Chu Luoxun' smiled even brighter, of course, and hugged Lin Meiyue, saying, it was too bad that she was not a man, otherwise, she would marry her!
