It's a rather trash average story, so I guess reading up to 10 chapters should be alright before dropping, *followed*.
Also why are mangakas and other authors so lazy that they just copy-paste the moon as it is. Why not be a bit more creative instead. How it is possible that two separate moons have the same impact craters on the surface... If you can't have good and unique story, at least compensate it with characters or the setting. Adding a separate similar moon is just meh.
Also what is the point of that Yuki girl? Is she there only to say how the op and cool and great the mc is? Don't we have that Efi for that? Is she her double because reader has to be told how great MC is at every occasion but Efi can't be all the time with him?
Welp, I've certainly written a bit too much but whatever, I'll read this story anyway if there's completely nothing else to read..
