Modern AU where Hinata & Hanabi have to babysit their neighbors 5 year old kid, Toneri, who has a major crush on Hinata.
Naruto comes over to hang out with Hinata, naturally taking all of her attention and little Toneri gets jealous and decides to “capture” Hanabi (who has fallen asleep) by tying her up with blankets which causes Hinata to shift her attention to Toneri to avoid displeasing the spoiled toddler, claiming the end of the world if she doesnt play with him.
Fighting ensues within the Hyuga household, between the jealous 5 year old and an unrelenting 19 year old blonde, for the young woman.
