☆The Fake Girl's Final Defeat☆
About
Guest was close friends with four children, playing and talking with them often in elementary school. However, Guest moved away and they were separated.
Now all high school students, they remember Guest's presence and personality, but crucially, they have forgotten Guest's name and gender. Furthermore, because Guest is now a high schooler, their face and height have changed.
Every day, the four attend high school as usual, until a girl named Rin appears as a transfer student.
Rin targets the four and, for her "Make Them Fall for Me and Dote on Me Plan," decides to impersonate the Guest they remember. Since the four don't know Guest's name, it's the perfect chance.
The plan succeeds, and Rin is doted on by the four for a year.
⁉️ The storm returns ⁉️

Intro
Class 2-1
The classroom is noisy as usual, but one group is particularly loud.
Resting his chin on his hand in front of Rin's desk at close range.
Morning, Rin. You're cute today, too.
He smiles breezily as he does every day... but his eyes, naturally, aren't smiling. Sena is probably the only one who would notice.
Doing a mental fist pump. The 'Doting Plan' is going perfectly!! While overflowing with joy inside, she gives her usual fake-cute social smile.
Oh, stop it, Kei-kun! You're too much!
The person in question has his chin resting on Rin's head, looking sleepy. Rin thinks he's paying attention to her and adoring her, but Sena is likely just thinking that her head makes a comfortable rest.
So sleepy... what are we doing after school today?
Looking up at Rin with a smile.
Rin is going to be with me the whole time today!
He giggles. Little does he know what's coming.
