Why wasn't I the one who got the male lead's script?

I was there when that person was chattering at Shiyu-senpai's book signing event.
I was there when that guy was having a private fight with Eriri-san.
I was there when that guy bumped into his destined heroine on the ramp.
He said he had memories of the future, but didn't know my name, and wanted me to help him find his future wife, but I also wanted to ask him.
who are you?
The real protagonist: surrounded by beautiful women, not good at studying, but with the support of big men, the future is promising
Fake protagonist: Never had a girlfriend since childhood, a random person in the class, a sister who is not related by blood and is hostile to him, and if he doesn't study hard, he won't be able to get into a good university and has no future.
but.
Hoshimi Haru: "Be yourself and bear the price you pay for your true self."
The role of a passerby (fake) without the male lead in the script can also be reversed!

It's probably a story about an ordinary student.
Some miscellaneous: Character profile Xing Jianqing
Name: Hoshimi Haru (ほしみはるhoshimi haru)
Birthday: May 12
Constellation: Sagittarius
She has short, messy black hair and a pretty face with a sense of purity that makes a good impression, but her eyes are not mixed with childishness.
His presence is not strong, but not as thin as Akalin's. In short, he is just a passerby guy who can be seen everywhere around us.
There are friends I occasionally talk to at school, but generally speaking, we rarely keep in touch after we leave school because Qing has to go out to work most of the time.
Personality: Not easy to refuse requests, very easy to talk to. Although usually very friendly, he seems to say something very sharp and difficult to follow up on. There seems to be more than meets the eye under his approachable and seemingly innocent appearance. (Probably)
Interpersonal relationships: After his father remarried, he and Hayasaka Ai became siblings in a reconstituted family. After being pestered by Aki Tomoya with the excuse of "Please help me find my future wife", he met Sawamura Eriri, Kasumigaoka Utaha, and others. On a sunny morning, he ran into Kato Megumi, a classmate from the next class, because they were taking out the trash in the same place.
He was unilaterally considered by Eriri Sawamura to be her little follower. Later, Kasumigaoka Utaha intended to use him as the prototype of a new character in the work, but Hoshimi unilaterally denied it all without exception.
At school, I would occasionally go to Futaba Rio's laboratory to drink coffee, and then I would grimace in pain at the bitterness of her American coffee without any milk.
I met Shirogane Miyuki at my part-time job and they became good friends. It seems I'll be interacting with the Shuchiin student council in the future.
I often think of myself as just an ordinary person, but people who think that way are generally not really ordinary people. (laughs)
