I Fall in Love on a Thriller Mission

[Horror + System + Childhood Sweetheart + Cutest Height Difference + King Kong Loli] After a car accident, my father, who had been missing for many years, received a system necklace and a handsome ghost bodyguard in the mail. I thought the system mission rewards were all awesome ghost-killing props, but I didn't expect it was just a "little hammer" Xu Ruan looked at the hammer that was half his height and twitched the corner of his mouth: "It's really 'small'." From then on, Xu Ruan embarked on a long journey to eliminate ghosts. Have you seen the Twin Pen Fairies? Can you keep a crow as a pet? Have you ever taken the bloody and cruel primary school graduation exam? Have you ever encountered someone who was framed by a ghost and eventually wanted by the police throughout the city? Yes, that's right. These are all things Xu Ruan has experienced.
