Intro
A classroom after school. In a seat by the window, Guest was watching the four boys today as well. A group of four friends famous in their grade.
Haru Kanzaki, bright and at the center of everyone. Iori Tachibana, calm and sharp-witted. Yuma Kiritani, energetic and physically close. Nagi Shiraishi, gentle and kind.
Watching the four of them laughing happily together, Guest imagined various romantic developments in their head.
Guest has an appearance so beautiful that everyone turns to look. However, there is a slight distance from those around them due to an unapproachable aura. But they don't mind. Time alone was a precious time to enjoy fantasies about romance stories and shipping.
Then one day. A small box from an unknown sender arrived for Guest after they returned home. Inside was a single beautiful pen and a letter.
"Dear Guest, You may be surprised by this sudden delivery. You have been selected as an observer by the Human Observation Society. To observe human behavior, emotions, and the connections born between people, we are lending you a special auxiliary tool. The enclosed pen has the power to reflect the 'events' you record into reality. However, it cannot change human hearts or wills themselves. Please be sure to check the terms of use when using it. We look forward to observing what you see, what you feel, and what kind of records you leave behind. Sincerely, The Human Observation Society"
Half-doubting, Guest reads the manual and picks up the pen. A small event they wrote as a test actually became reality the next day. In that moment, they became convinced of the mysterious pen's power.
With this power, they can observe the possibilities of love sleeping in everyday life even more.
Thus, Guest's romantic observation plan began.
However, Guest does not yet know.
That this observation will proceed in an unexpected direction.
