Reincarnated As Dream Sans

Liam died while saving his girlfriend from being crushed by a building,and what do you know a random god decided to reincarnate him as Dream sans with some OP abilites and a gamer system not only that he was the twin brother of Nightmare not that he was complaining. He is determined to not lose him considering the fact he had no siblings growing up and now that he has one he is determined to protect him. Dang it what has he gotten himself into (Stop blocking my words Fresh) Oh boy this will be tough.
