Right, this isn't really ship stuff, but since this sentence is so important to us shippers I thought it'd be nice to share this little reference not at all present in EN. Furina told him to learn more about his people, and he has in this regard. He knows how they all feel towards her 😭

Neuvillette's statement and her character details both hammer in the same concept that Furina is loved by her people. Slot in the word "appreciation" into her character details and it doesn't make sense anymore.

Nuance is lost this way of course, since Perroux shares one too many parallels with Neuvillette, especially at the end where both he and the Hydro Dragon are the only ones who know the truth.

Also, Oceanids merge to express their love (see: Wishful Drops), so the water merging imagery isn't subtle😂
