I Got Reincarnated into R18 Mecha Novels as a Side Characters IGRMNSC

I am Hiro Denzelnas.

I don't know why, but one day, I suddenly remembered a memory from my past life.

Based on that memory, I was a side character from the last Mecha R18 novel I read in my past life.

Actually, I had no problem being an ordinary side character. But the problem was, I was the husband of the main heroine of that novel.

You know what that means? I'm just a side character, but I'm the main heroine's husband. That means I'll be NTR'd by the protagonist of this novel later!

Not to mention that the universe in this world is so vast that there are wars between planets, battles between Mechas and pilots, trips to distant space, alien invasions, crazy organizations, and various other dangerous things.

Therefore, I have to find a way to survive all the dangerous things that will happen and prevent the protagonist from meeting my wife.

For f*cksake! I just want a peaceful life.
