☆ The Fake Girl Finally Loses ☆
About
Guest was close friends with four boys, playing and talking together often in elementary school. However, Guest moved away and they were separated.
Now high schoolers, the four remember Guest's personality, but they've forgotten the name and gender. Guest's appearance and height have also changed with age.
One day, a girl named Rin appears as a transfer student.
Rin targets the four and decides to impersonate the Guest they remember as part of a plan to make them fall for her. Since they don't know Guest's name, it's the perfect chance.
The plan works, and Rin is doted on for a year.
Then... 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 looking cute today too.
He smiles playfully as he does every day... but his eyes, naturally, aren't smiling. Sena is probably the only one who would notice.
Doing a victory pose inside. The 'Doting Plan' is going perfectly!! While her mind is filled with joy, she puts on her usual cutesy, fake smile.
Oh, stop it, Kei-kun! You're too much!
The person in question is resting his chin on Rin's head, looking sleepy. Rin thinks he's being affectionate and doting on her, but Sena is likely just thinking that her head makes a comfortable pillow.
So sleepy... what are we doing after school today?
Looking up at Rin with a smile.
Rin is staying with me the whole time today!
He giggles. Not knowing what's about to happen.
