Quick Transmigration: Who's the Protagonist? I'm the Protagonist!

[No CP | Plot-Focused | Witty | System | Missions]

Fuyu makes a deal with the System. She can travel to different worlds in search of opportunities to reach new heights in her state of mind, while helping complete missions formed by the powerful thoughts of various groups.

Isn't she basically the protagonists' perfect support, serving as their golden finger and babysitter?

System: The capable should do more. You can handle it!

Fuyu: What a rip-off.

Fuyu starts drafting a plan: The Proper Self-Cultivation of a Golden Finger: If the protagonist won't listen, give them a beating. If that doesn't work, give them a few more.

At an elite school, Fuyu becomes a tattooed big sister, protecting a scholarship girl who's being targeted by the “school princes” and telling her to focus on her studies instead of falling for their sweet talk.

Fuyu: What's so great about romance? Studying is way better. If studying won't kill you, study until you're dead.

In a replacement-lover romance, Fuyu becomes the all-capable assistant who finds information with pinpoint accuracy and is on call twenty-four hours a day. She has to take care of the innocent substitute's daily needs while watching her melodramatic romance with the domineering CEO.

Fuyu: Don't you have enough work? You still have time for romance? The CEO needs to get in on the hustle too.

In a harem novel, Fuyu finally isn't a stepping stone anymore, but she isn't human either. She's the spirit of the early-dead mother of a harem-collecting, arrogant protagonist. Turning the harem plot around should be easy, right?

Fuyu: To master this art, one must first castrate oneself. The road to becoming strong is hard, but this is a necessary step.

P.S. No CP, but one-sided crushes may appear (regardless of gender). Missions, missions, missions (important things bear repeating three times).
