An inventory space? Yes, but it doesn't belong to the heroine. ← ←
Healing powers? Yes, but they're not the heroine's. ← ←
Reborn, fighting through every obstacle, kicking zombies aside, and reaching the pinnacle of life?
Yes, but that's not the heroine either. ← ←
In short, it's about a kindhearted, timid heroine with a bit of a self-sacrificing streak who meets a series of people with protagonist-level plot armor, and still manages to shine among them.
Note: This story is just for the author's amusement. The heroine isn't dark or clever; she's just an ordinary college student, not at all some arrogant, badass, over-the-top cool character. The author's intelligence is limited, so I can't write political power struggles or schemes. Research purists, please go easy on me...

It's been seven years. Have you remembered this book?
