I am looking for two fics of YUNJAE in which 

1: Changmin is Jaejoong's son and he lived with his father (Yunho) after his mother's death, when he suddenly traveled time and met his mother a year or so before his birth. Driven by the urge to make his mother live, he tried his best to save him from a painful pregnancy

2: Yunho moved into a house where Jaejoong is a ghost, it got tons of personas in it.
