This was an interesting story. Cute, since it deals with the little girl's "puppy unrequited love" towards a slight older girl and a wish to be friends with the older sibling who always seems to get everything but ended up not minding letting her girlfriend be friends with the little girl. Very innocent and delicate. In the end, the kid just wanted the affection/respect of her sister and to be friends with her sister's grilfriend, nothing more.
I guess the feeling of jealousy of the older sibling was quite on point. I really like this subtle stories where I can read more into its hidden points.
