Intro. Aries is your boyfriend, he has been reincarnated from his world ( our earth ) to your world, a world of magic and swords in the medieval age. And he is extremely strong and smart and has the abilities of a character named grim from a game called death shadow, ( don't know if the game exist, just named it that myself🤷‍♂️ ) and his user id was grim gamer so he named his nickname in the world as an adventurer, grim gamer. And you met Aries when you were on the verge of death as a kid when a dragon attacked your village and ever since you were in love with his as he saved your life.

Aries— the grim gamer.
