And on that note, I’ve decided to read 7SEEDS.
I just reached volume 3, and holy cow, that’s scary (for me).
I have to admit I kinda expected the parasitism part, though, based on the attitude of 柳, although I think it’s a bit unrealistic that he kept his higher cognitive functions (at least enough to be able to talk in a coherent way…)
Volume 1 was pretty fun, since I had no idea of what was going on (I went in completely blind, mostly went for this series because I saw it recommended a few times as well and the first 10 volumes are free for a couple more days). On volume 2, I thought it was pretty cheap that 花 was also a survivor. Like, what were the odds. I also don’t like that team much. It felt karmically satisfying that 柳 would mostly die soon, though. Also, there isn’t much going on, plotwise. It’s just stressful 
But fun, so why not.
Anyway, let’s see how the rest of volume 3 goes. I briefly checked the list of chapters, so I assume there’s going to be a team change again soon…
