As of ch. 47:
I decided to give this a try after reading another work of the author despite the questionable description and reviews. I'm glad I did.
The story and the occasional dub-con is definitely questionable. However, it's not to the extent referred to in the reviews. What "the MC gets r*d to death in the first world" and "ML just kept the f*cking corpse like nothing happen till he was tranquilised"? There is definitely some exaggeration here. Here is the actual end of the first arc:
Spoiler
The ML definitely forces intimacy way too early in their relationship over something really s*upid. This is undeniable. The MC is still 'alive' when the ML leaves the room the morning after and even reminisces over his enjoyment over the latter half of the night. His system alerts that the mission has been completely and his soul leaves the body. The ML comes back and cannot accept that the MC is dead. He chastely hugs the body and lives a few days in denial with the corpse, even trying to feed it breakfast. This isn't necrophilia, it's extreme grief combined with guilt. The tranquilizer scene is when his family takes the body away to be buried, but ML is trying to fight them over it. He does a bad thing, but he definitely gets his just deserts.
Incidentally, it is revealed at the beginning of the next arc that the cause of death is not the night of s*x. It turns out that the MC is always inhabiting these characters upon their death, which somewhat suspends the fatal injury. The original host of the first arc was already dead from an injury to the head in the very first scene. Official cause of death is the resulting brain clot. So in this sense it *might* classify as necrophilia, but the ML is definitely not aware that the MC is inhabiting dead bodies considering the MC appears very much alive.
It looks like the main couple of this work will be another pair of baddies doing their best to hurt and love each other. I just might keep reading anyway. I'm somewhat curious about the 'why'. There is almost always a reason in this genre for the couple to be able to follow each other through transmigration (assuming this is that kind of story). The MC likely has some pre-existing tie to the ML or the original hosts or both. What makes him special? What has the ML done to make destiny so determined to break his heart? The slag shous weren't enough, so the MC comes in to really hammer it in??? Is this punishment for the MC or the ML or for both of them? So many questions and I can only read to find out the final answers. :)
My current rating is about a 3.5 or so. I am a sucker for tragedy. Unfortunately, I am not a sucker for dub-con or dramatic transmigration scenarios. I will raise it to a 4 later if the ending can make me weep.
Update:
Well... I didn't weep. It is a big bonus that the real life arc was much longer than expected and full of it's own ups and downs. The extremity of the early worlds and the reason for him to be chosen does get explained at least.
Spoiler
In retrospect, an elder (?) sent them on a massive virtual blind date in the name of science (?). They could be considered a cross-species relationship both physically (ML much stronger than any human) and culturally (ML raised to be a weapon). The elder/doctor that caused all of this to happen is the most questionable character in the story.
The doctor is the main drive behind the attempt to humanise the ML who carries alien genes even though and the ML are likely the last traces of their race. He won't let anyone disparage the extinct alien race, yet seems to have no intent on bringing them back beyond a fondness of the ML. Both he and the ML do not seem likely to have children since they have each partnered up with male humans.
Speaking of, what happens when the MC dies of old age? ML will likely self-destruct or start destroying planets...
