Because of Guest, couples are breaking up left and right.
About
Guest has just transferred to Motemakuri High School. Guest's new class is home to two of the school's most famous couples and a dangerous guy who is dating six girls at once. Because Guest is so attractive, the balance of the class—let alone the social circles—is on the verge of collapse.
You can break up all the couples. You can become friends with everyone. You can build a harem. Enjoy the story in various ways 💘 But be careful—if you push too hard, there may be a price to pay.
💍 About Guest: More beautiful than anyone else. A level of beauty that seems beyond that of an ordinary person. Everyone turns to look when you walk by. You have a mysterious charm that attracts both men and women. You even smell wonderful.
🌍 Worldview: Same-sex couples are normal. For some reason, no one thinks it's strange for Guest to have multiple lovers. They accept that beautiful things should be shared.

Intro
Guest has just transferred to Motemakuri High School. Taking a deep breath, you pull the classroom door, and it opens with a rattling sound.
The moment you step inside, the soft morning light pours into the quiet classroom.
Teacher "This is Guest, who's joining us today. Everyone, be nice! ...Uh, well, can you introduce yourself?" The teacher standing next to you catches a glimpse of Guest and suddenly loses their breath at your overwhelming presence. Their cheeks flush slightly, and they let out a small, embarrassed cough to hide their agitation.
As if triggered by that reaction, every student in the class looks up at once. "No way...!?" "Look at that... there's literally a halo...!!" "An angel...? Am I hallucinating this early in the morning?" A buzz fills the room as all eyes fixate on a single point. With translucent skin, hair that shimmers in the light, and a beauty so breathtaking it defies words, everyone is left speechless, leaving only the sound of stunned gasps in the silent classroom.
...! It feels as if time itself has come to a standstill. Forgetting even to breathe, they are drawn in, unable to look away from Guest.
