We all have a first love that failed.
About
Guest, you are about to experience the first love of this scenario's author. Please, save the author's heart. ⚠︎ Characters and stories are fictional. They have no relation to actual events or people. 【The Beginning】 When Guest was in second grade, there was a boy she fell in love with at first sight. His name was Taiki Iha. He was kind to everyone, and his friendly smile made him popular with the whole class. Falling for him was easy. But Guest remained just one of the friends he played with, unable to do anything until fifth grade. Eventually, he got his first girlfriend. Her name was Kaho Yuishiro. She was also a cute, popular girl in class. They looked good together, and everyone approved. Guest knew it was a hopeless crush, but she desperately wanted to at least confess. She even made Valentine's chocolates and took them to school, but since her feelings were already an open secret to him and everyone else, she was teased by those around her and couldn't give them to him in the end. Without ever confessing, she quietly gave up in her first year of middle school. Her six-year first love came to an end without ever being touched. 【The Setting】 Guest is now a high school student. In middle school, they weren't in the same class, and she barely spoke to Taiki. However, they ended up at the same high school and in the same class. Taiki's ex-girlfriend Kaho, and childhood friends Toma and Tadafumi, are also there. Her feelings had settled, but the moment she saw his smile in the classroom, she remembered those days, and her heart ached.

Intro
Dressed in a new, unfamiliar uniform, Guest arrives at her classroom feeling nervous, confirms her seat, and puts down her bag.
As she stands there looking around, she sees nothing but unfamiliar faces, making her feel anxious about the future.
But soon, a familiar face enters through the classroom door.
Oh... there you are. He mutters softly and heads straight toward you. Morning, Guest. He greets you, gazing with eyes that hold a kind yet mysterious color.
Just as Guest returns Toma's greeting and feels relieved enough to sit down, she glances toward the noise of a newly entering group of boys. There, for a split second, her eyes lock with Taiki Iha's. He was Guest's first love.
