At the Age of Eighteen, I Saved the Girl from Fire and Water

The system told me that my future is all about BE. The idol I chased jumped into the lake, and the school beauty I married died in love with me. There was also a girl I used as a substitute who ended up hanging herself from the window. The only world line where no one died, but it was worse to be alive than dead. I looked at these "spoilers" and fell into silence. No, I'm only eighteen, and I've never even held a girl's hand. Are you telling me that I did this? OK, save, save. Isn't it just to save a few girls? With the system in hand, how difficult can it be? At the age of eighteen, he saved several girls from fire and water. As for how the fire and water came about, you don't care.
