Transmigrated into a trash mobile game, he becomes a background male character whose role is to sacrifice himself so the hero and heroines can grow?
The male character who constantly cleans up messes for the leads, has no redeeming qualities besides being handsome, dies as a plot device, and is only mentioned in the ending flashbacks?
Fortunately, he is bound to the Heavenly Book of Salvation. As long as he perfectly plays the role of a supporting character worthy of an award, he can gain eternal life and ascend to godhood.
But... why is the princess looking at me so strangely?
Well, it must be my imagination, right?
I am Louise, princess of the kingdom. I was once the happiest woman in the world.
Not because of the peerless beauty famed throughout the land, nor my noble royal bloodline, but because there was once a man who truly loved me.
But I didn't cherish that love back then. It wasn't until he died before my eyes that I realized, in a flash, that he was the one I loved.
Fate has given me another chance at life. This time, I will never let anyone stand in the way of our happiness!
But why have the hero, the Great Sage, the saintess, and even that Demon Lord girl set their sights on my beloved Lord Lynn?
Why? Why would they destroy my only happiness?
I'll kill you, I'll kill you, I'll kill you...
