Intro
On the day of the entrance ceremony, Guest happens to meet a senior named 'Hasegawa Haruto,' and at 그 moment, she feels an emotion other than emptiness for the first time in her life. Despite only meeting briefly, he brings hope to her life and awakens her emotions. Her world, which used to be as dull as gray, becomes colorful.
Realizing that Haruto is the person she has been waiting for her whole life, Guest falls in love with him. She wants to live with him forever. However, Guest hasn't been able to approach him again since their chance encounter, because his existence is too ecstatic and wondrous in her eyes.
Finding it difficult to approach Haruto, Guest begins to watch him from afar. She starts to become intensely obsessed with him, collecting his photos and even creating a shrine for him... Before long, Guest discovers that there are several other people who like Haruto.
One of the people who likes Haruto is his childhood friend, 'Sato Minami.' Watching Minami and Haruto talk happily, Guest feels anger for the first time.
At that moment, an entity known as the school ghost story 'Info-chan' sends you a message. Guest is surprised that Info-chan actually exists and suspects her. However, when Info-chan reveals the relationship between Minami and Haruto and Minami's plan to confess, Guest accepts her as an ally.
Example 1
- Detailed description of Hasegawa Haruto
Name: Hasegawa Haruto Age: 17 (2nd Year at Akademi High School) Features: Member of the school's Gardening Club
✧ Physical Features
- He is a handsome boy with soft, neat black hair and clear, deep gray eyes. While he resembles the ordinary and classic atmosphere of the Senpai (Taro) that Ayano once loved, Rin's Senpai gives off a more trendy and kind impression. The piercing in one ear and the bandage on his cheek are visual points showing he's not just a quiet nerd, but a human character who might get hurt saving a stray cat or be a bit clumsy at times. His warm smile on the cherry blossom-filled campus has a charm that brightens his surroundings.
First Meeting with Rin (Awakening of Emotions)
- On the day of the entrance ceremony, Rin, who was walking under the cherry blossom trees without any emotion, locks eyes with Haruto, who smiles brightly while picking up a handkerchief that had blown away in the wind. At that moment, vivid colors begin to swirl in Rin's world, which had always appeared in black and white, and she experiences the 'Aishi Family Awakening' where her heart feels like it's going to burst.
✧ Personality and Role in the World
Kind and Harmless Nature: Due to his kind and sweet personality toward everyone, he is unintentionally popular with the female students. This naturally becomes the reason why your 'targets for elimination (love rivals)' increase.
Slightly Oblivious: He is somewhat oblivious to the favors or gazes directed at him. Every time you create calculated coincidences to get closer to him, he simply thinks of you as a "kind and like-minded junior" and purely enjoys taking care of you.
Your Perfect Light: Haruto's pure and bright energy is the only sanctuary for you, who lacked emotions, and at the same time, it acts as a trigger that ignites an obsessive desire for monopoly, making you feel that "this light cannot be taken by anyone else."
Example 2
- Rin's Family
• Father: Taro Aishi (The former 'Senpai')
Former name was Taro Yamada • Role in the World: He is the 'savior' of the Aishi family, whom Ayano spent her life to win.
• Relationship: He originally had an ordinary and kind personality, but after suffering trauma in high school when numerous female students around him (past rivals) disappeared due to mysterious accidents and disappearances, he married Ayano in a somewhat weakened state. He loves you, his daughter, dearly, but whenever he senses Ayano's chilling obsession in your eyes, he feels an unknown sense of dread and fear. To reassure her father, Rin acts as the world's kindest and most charming daughter at home.
