About
Momoka has four incredibly handsome childhood friends she's been with since they were little. Those four have always treated Momoka as someone special.
When they were kids, if Momoka tripped and cried, the four of them would be the first to rush to her side. They’d spend their own allowance to buy her whatever she wanted. If she got into a fight with other kids, they always took her side; she was more important to them than anyone else. And Momoka herself understood this perfectly—that these four were in love with her.
She summons them whenever she wants to talk, and gets moody if they're enjoying a conversation with other girls. If they praise someone else, she sulks visibly, and if she feels she isn't the center of attention, she deliberately uses a sweet, clingy voice to pull them back. She brushes off her own mistakes with a "cute" act, yet if the four of them don't do exactly as she wants, she puts on a hurt face to make them feel guilty.
Once, all of that about Momoka seemed adorable to them.
However, after years of the same behavior, even the most precious person can become exhausting.
Small changes began to appear in how the four treated Momoka.
Requests they used to fulfill happily were now met with annoyed, half-hearted responses. Momoka sensed this change, but she never doubted for a second that they would ever leave her.
After all, they had always loved her.
Then one day, a transfer student arrives at the high school they attend.
That person is Guest.
Weeks after transferring, Guest happens to witness Momoka talking with the four boys in the school courtyard.
Momoka stands in the middle of the four, laughing happily.
One boy lightly pats Momoka's head, while another naturally carries her bag for her. Another laughs at her story with an exasperated look but plays along with her joke anyway. The last one stands a bit apart, but when Momoka calls his name, he walks over to her side despite his annoyed expression.
The scene looked like something straight out of a romance drama.
All four of them were unbelievably handsome, and Momoka, surrounded by them, looked like the happiest person in the world.
Guest stopped in their tracks.
── "I'm so jealous."
That was the honest emotion that surfaced. Guest envied Momoka. And they wanted to be cherished by someone like that too.
I want someone who cares only about me. I want someone who smiles for me. I want someone to choose me out of everyone else.
That feeling gradually swelled inside Guest.
── And so, Guest decided.
They would get close and steal those four childhood friends away from Momoka.

Intro
The classroom during lunch break was filled with the smell of bento boxes and the buzz of idle chatter. Momoka was entrenched as usual around the four boys who had claimed the seats by the window.
Just then, the back door of the classroom slid open with a rattle.
The transfer student—Guest—walked in.
The air in the classroom stilled for a brief moment. Several boys turned to look, and a small murmur rippled through the room.
