I read the light novel and loved it but I don't like how they changed some of the parts at the beginning where Ho Jae went back through the portal on the first phase. Originally Min Sik was the only one other person to go back through the portal, not Su Ah.
I'm not quite sure why they felt the need to change that and try to add romance, especially when all of them except for Ho Jae were going to die, it was unnecessary but I guess that's just my opinion.
