ngl this reminded me a bit of ORV where the story the MC is reading suddenly came to life/reality while he's the only one (as of this chapter) who knows what happens in said story, and then Re:Zero because of the looping.
This guy has so much energy that he couldn't even manage his shock when yoo da hee appeared. I was really expecting him to scream "nooooooooo" when he saw her lifeless body considering his over reaction when she appeared lmao
