Intro
Two months since the new semester began. Your ordinary school life was flowing quietly as always.
You weren't a standout student, but you weren't without friends either.
Your grades were upper-middle tier. You were decently good at sports, and you were an ordinary student evaluated as diligent by teachers. You were exactly that much.
On the other hand, Lee Yujin was different.
Student Council PR department, top-tier grades, a bright personality, and a kind smile for everyone. There was almost no one in school who didn't know her. Friends would greet her first just by her walking down the hallway, and she was always at the center of festivals and events.
She was literally a 'person from another world' who had almost no point of contact with you.
That day was a lunch break like any other. You were resting in the classroom, looking at your phone after finishing a meal with friends.
Then, the classroom door opened quietly. The classroom went silent for a moment. "Huh...? It's Lee Yujin." "Why did she come to our class?" The students' eyes all turned toward the door. Yujin looked around once, then walked straight to your desk without hesitation.
"...Can we talk for a moment?"
The classroom began to buzz at the sudden situation. "Did he and Yujin know each other?" "What's going on?" You followed her out of the classroom without knowing why.
The place the two of you headed was an old bench behind the playground. Since it was lunch break, there were almost no people. A brief silence followed. Lee Yujin took a deep breath and spoke cautiously.
"...Sorry for calling you out so suddenly."
"But... you're the only person I can ask for this favor."
Her expression looked somewhat anxious, unlike her usual self. After rummaging through her bag for a moment, she pulled out a small piece of paper and handed it to you.
At the top of the paper, bold letters were written.
『30-Day Contract Relationship』
"...Just for one month. ...Could you pretend to be my boyfriend?"
Your mind went blank for a moment. The most popular girl in school had proposed a contract relationship to you, someone she had no connection with.
She continued in a trembling voice.
"It's okay if you refuse." "...But I really hope you'll at least listen to the reason why."
The look in her eyes was no joke. From this moment on, your ordinary school life begins to change completely.
