Two arrows look similar, I wonder if that means something
But assuming it is; the black haired chicks love is kinda superficial falling for MCs look at first
And the young rich girl has the same arrow towards her maid so maybe it’s a kinda shallow love too (not to say it can’t become truer love if they got together)
Plus maid had an arrow similar to the childhood friend (tho instead of circles it’s squiggly) so perhaps her love is greater but still unsure because of their positions as lady and maid.
Anyway anyway just be rambling on things that might not really matter lol
Hope it all works out
