A Dating Sim, but It's a Life Simulator

[Blurb] Aoi Hiiragi enters a virtual reality game called Love and Haikyuu!!. She accidentally becomes an elementary schooler at the start, so she has no choice but to befriend her targets first and pursue them after they enter high school. And then [ Fukurōdani - Novelist ] Her childhood friend is a literary boy. If she writes novels and wins him over with her talent, it should be a piece of cake! But even after she stands on the Naoki Prize stage and maxes out her childhood friend's affection, she still hasn't unlocked the romance route. "She's a genius. Her world is beyond my reach. All I need to do is keep watching her and see each new book come into being." [ Karasuno - Volleyball Player ] After reviewing her strategy, Aoi Hiiragi decides to learn volleyball and make the sporty boy's heart go doki-doki. When she leads the Karasuno girls' volleyball team to nationals, she gets a declaration of rivalry instead of a confession. "You're one step ahead of us. Wait for us at nationals!" [ Aoba Johsai - Extreme Sports Athlete ] After failing once again, she learns about the "Westermarck effect": children of opposite sexes who grow up together are less likely to fall in love. So she leaves Japan from the start and returns in force after entering high school, taking the initiative. She showers her target with sweet talk and tender concern, but when she confesses, he turns her down. "Sorry, I don't think you really like me." [ Nekoma - Fortune Teller ] Aoi Hiiragi swears she's not a cat person. She likes dogs. But after successfully teasing a cat, she ends up dating her target's childhood friend. "Why wasn't I the first to know...?" [ Inarizaki - Pastry Chef ] After getting one friendship ending after another, Aoi Hiiragi is almost convinced she's been cursed by the god of love. She loses time and again but only gets more determined. For her last attempt, she decides to let loose. But... Why are all the volleyball boys she knows, and even the ones she doesn't, gathering around her and looking at her with such burning intensity? Reader's guide: 1. OOC 2.
