Infinite Flow: I Picked Up a Dog in a Deadly Game

(I feel the pacing of this book is too slow, so I'll set aside time to completely rewrite it, starting from the chapters where the characters enter the instances. Stay tuned!) Their bodies are captive, their souls on the run. [Two male leads / survival / pure love / mutually exclusive devotion / both inexperienced / fated / happy ending] A mysterious killing game suddenly appears, sweeping across the country and forcing all young adults who have come of age to take part... While most people fight for their lives, even turning on one another, a select group rises above the rest. They are the true endgame of this vast game... In the terrifying killing game, Fang Wu accidentally tugged at someone's heartstrings. But for various reasons, he also hurt that person's tender heart. That person is tormented as he falls into a spiral of conflict and struggle, eventually breaking through his own defenses bit by bit and growing stronger... Before long, Fang Wu realizes that this person really means to stick to him, just as he said... The man is like a shameless, lovesick mad dog. No matter how Fang Wu drives him away or treats him coldly, he refuses to let go. As things go on, Fang Wu can't tell whether he's slowly being won over or gradually drawn in... If he could look inside his chest, he'd see that his heart has long been beating in sync with the other man's... When two hearts from different worlds fall into an unfathomable whirlpool of love, what must they do to remain entwined forever?
