Avoiding Death in an Otome Game

Kai Shen, son of a Marquis recovers his past life memories and realizes that he is in the world that's identical to an Otome Game he played 'by chance' in his previous life.

But he doesn't have any intention of making harem or bringing an industrial revolution like your standard isekai, because here his life is at stake!

His character Kai was supposed to be an arrogant and cold hearted noble kid who dies in the game no matter what route the heroine takes!

Now how to avoid death?

Ditch the 'School'? Not possible!

Avoid the 'Events'? Too unreliable!

Then he came up with an idea “I will not die if they can't kill me” and he started practicing magic without realizing that he is raising several new flags.
