Review Detail of Serendipia_ in Nightmare Shuttle [BL]

It is the first time I read about a yandere or psychopathic protagonist, and I must admit that I love seeing how he behaves, his way of seeing things and what to say when he laughs at everything catastrophic that happens around him. In addition to the world in which it takes place, I love it, especially because it contrasts with the MC's personality, since everyone else suffers from being in that game while he enjoys the game, it is like the arrival of a demon in his territory.
