[Reborn!] Why Is Everyone's Affection at 100% from the Start?

Fujiwara Takashi discovered something. Why did the future Tenth Vongola Boss have a 100% favorability rating above his head?

She also discovered that the popular baseball boy had a 100% favorability rating.

Then she discovered that the new Italian delinquent had a 100% favorability rating too!!!

The problem was, this was their first meeting.

Fujiwara Takashi had no idea what was wrong with the System. In a daze, she was invited to the Sawada home. Nervously, she glanced at the world's greatest hitman, who was wearing a baby's disguise. Phew, thank goodness. Not 100%. Just 90%.

?! What? 90%?!! Why is it so high?

She opened her eyes wide and met a pair of pitch-black eyes that seemed to smile without smiling. Her horrified expression made the rating rise from 90% to 91%.

...Is this really the proper Katekyo Hitman Reborn world?

* An everyone-loves-her otome story, with lots of one-sided crushes. Don't ask me who the male lead is. Mainly Katekyo Hitman Reborn, but Detective Conan and Jujutsu Kaisen also appear.

* The girl often hits a nerve without meaning to, so everyone is always on the verge of going dark.

* No angst. The female lead has a pretty ordinary, average personality. If that bothers you, don't read.

* Everyone gets their time in the spotlight. All the characters listed as supporting characters are ones I plan to write.

* Includes a small amount of meta game elements. Remember, this isn't just a game.

Theme: I tried to be an extra, but I'm actually the center of everyone's attention.
