Has Gojo Won Yukimura Over Yet?

[This story is complete. I'll open a separate spin-off thread later, where you can read all the extras for free.]

Also known as "100 Ways to Win Over Yukimura," "100 Ways to Pursue Yukimura," and "My Target Is the Beloved White Moonlight of the Entire Rikkai Team"

Hello, player. Welcome to the [Otome Game].

Your objective: Win over the beloved white moonlight of Rikkai, the beautiful black lotus who is gentle on the outside but tough within: the Son of God.

System tip: Affection changes according to your target's mood, and you might even get a surprise drop, dear player!

Mission One [Bring Yukimura-kun a bento, current affection +1]

Itsuka Nanako deliberately hid her scalded hand behind her back.

Inside, she was happily calculating: I burned my hand making this grilled fish bento. Surely I'll get some kind of reward drop for that!

Mission Two [Bring Yukimura-kun your chemistry notes, current affection +1]

Yukimura smiled, holding the chemistry notes, and somehow managed to outshine a hundred flowers.

Itsuka Nanako sighed to herself. How could a chemistry notebook this thick be worth only one affection point?

Mission Three [Cheer Yukimura on at a match, current affection +1]

Yukimura-kun looks so dashing on the court!

Ah, Sanada-kun beside him is so handsome.

Huh? Atobe-kun from Hyotei across the court has such a sexy beauty mark beneath his eye!

[System tip: Current affection -1, -1, -1...]

Itsuka Nanako cried out in shock: W-wait a second! Why is my affection going down?

At this rate, when will I ever clear the game?

One day, 5t5 saw his younger sister come home holding a man's hand. The handsome man gave him a gentle smile. "Hello, Big Brother. I'm Nanako's boyfriend."

"I love you more than anyone else in the world."

Warnings:

1. Yukimura is the endgame, no changing my mind. The story takes place in high school.

2. The heroine is the youngest daughter of the Gojo family, an ordinary person with zero cursed energy.

3. Yukimura is extremely out of character.
