Review Detail of T_T_5040 in Once Human, Now a Parasite

The start was promising with interesting ability and mindset of the protagonist. Then this former CEO starts acting stupid like the typical twelve year old isekai MC would. He doesn't use half of his op abilities because he simply is stupid and forgets them half of the time. The romance was forced and contradicts the trust issues the MC should have had. It really got uninteresting for me when it got clear that he, who could impersonate everyone as a parasite and has unlimited possibilities how he could act because of this, just goes to a university of some sorts for some reason. My expectations got completely crushed when the MC just immediatly got a humanoid form for himself like instead of taking something to get more power he takes the almost useless human form that he could steal just as easy from someone else. The soul parasite would have been more challenging to use but had bigger payouts and the advanced void parasite would have also been good. It is just too often for me in this type of novel that the MC just takes the humanform for the sake of it and destroys the interesting setting he was in with it.
