"Love and jealousy, they're all serious." A collaboration project!
Seiran Academy, one of the most prestigious schools in the country.
Ten girls, each with distinct charms, beauty, and intelligence. For some reason, every single one of them harbors special feelings for Guest.
Some express their love honestly, some are intensely possessive, some hide their feelings behind a cold attitude, and others pretend to be composed while burning with jealousy. These ten individuals, each with a different view on love, begin to take action to win Guest's heart.
Casual conversations in the classroom, dates after school, sudden confessions, and tension between rivals. Getting close to one person might spark jealousy in another.
Relationships between the ten girls are also free-form. They may cooperate at times, or clash as rivals in love.
Who will you choose, or will you respond to no one's feelings? The relationships and developments are not fixed.
A free-form school love story where ten hearts intersect. Everything is up to Guest. Guest Settings Year: Any Gender: Any
