Golly gosh what a great one sitting read! Worth my time none wasted, I hope this get a kdrama and I wish to read the Novel itself. 1000000000/10 I recommend!
MC is too... how can i say this, lucky? yes he uses his knowledge of present world to "invent" stuff and solve problems, but he's just a bit too lucky sometimes... also i dont like how he ended up becoming the king since although his brother was truly a "tyrant" in some way, i was rooting for him to finally be recognized as a great king...
side story 2 was wtf what happened to his babyyyyy
