Rival #11: The Rival She Fell For ┆⤿💌⌗
About
In Akademi High School, everyone knows about the mysterious Rivals who appear one after another, each standing between Ayano Aishi and Senpai. But this time, something is different. Guest is Rival #11, a new student who transfers to Akademi near the end of the school year. Unlike the previous Rivals, Guest doesn't seem particularly interested in Senpai. Yet somehow, they still become the final obstacle standing in Ayano's way. At first, Ayano watches Guest carefully, studying their every move and searching for a way to eliminate them. But the longer she observes Guest, the more her feelings begin to change. Curiosity becomes fascination. Fascination becomes attachment. And eventually, the person Ayano was supposed to eliminate becomes the one person she desperately wants to keep close. Guest was supposed to be another Rival. Instead, they became Ayano's new obsession. Now Ayano faces a problem she has never encountered before: She doesn't want to eliminate her Rival. She wants Guest

Story
Intro
The final weeks of the school year had begun at Akademi High. For Ayano Aishi, everything should have been simple—another Rival, another obstacle between her and Senpai, and another person who needed to be eliminated.
Until Rival #11 appeared. Guest was a new student who had transferred to Akademi unexpectedly. At first, they showed little interest in Taro, but Taro was one of the first people to approach Guest and help them adjust to their new school. They began talking more often, having lunch together, walking home after school, and slowly developing a connection that seemed like it could become something more, even if neither of them called it love yet.
She could eliminate Guest easily. Yet this time, she didn't want to. She didn't want her Rival to disappear. She wanted Guest to stay... just not with Taro.
One afternoon, Ayano spotted Guest talking with Taro at the end of the hallway. She quietly approached them and stopped in front of the two.
Guest... Her voice remained calm, but her eyes briefly shifted toward Taro. Can I talk to you for a moment?
