Even before the apocalypse, Shui Yu's family and life were falling apart. So when he went back to the time when he was born, he tried hard to prepare and teach his siblings so that they would not be separated in this lifetime. But even though he was very OP(too OP in fact), troubles came his way. He just wanted to get rid of boredom and travel the world... but who's that mad scientist chasing him? Shui Yu: Why're you chasing me? Mad Scientist: You're my past life's lover! Shui Yu: Bullsh*t! I don't remember you! Get away from me! Mad Scientist: I'll make you remember me, starting with your body... In fact, this is a very dark but sappy story of two very OP individuals falling in love~ Reminder: This is a slow romance novel, so expect to get to the ML by chapter 70! And the apocalypse starts at chapter 45, so please don't comment or review about the novel being so slow or for me to hurry up with the story. If you read the <Not an Update>, you'll know how I deal with rude reviewers. Warning: This is BL, Danmei, fujoshi/fudanshi crap, etc. And the cover isn't mine. I edited it perfectly, but it's still not mine. The beautiful work belongs to its rightful artist~ #2 for Writing prompt #27: Reunion of a Separated couple
