Kinda surprised noone's made a thread about this manga yet...
So yeah someone told me to check this manga out since I said I liked other work by Yuna Kagesaki (Artist for 'Karin', and 'Onii-chan Control') at first it was kinda slow and pretty boring but as it gets further in its actually really good... well IMO...
Anyway yeah if you guys like good stories you guys should check it out...
Summary wrote...
Tsugawa Tatsuya just lost his parents in an accident... but he's trying not to let that keep him too down as he starts highschool.
While trying to obey his father's final wish for him to become an upstanding man, he ends up helping a girl who was being bullied. Despite her exceedingly cold nature, he just can't leave her alone... which may not necessarily be to his benefit, as he ends up getting wrapped up in a world where things like parasitic mind-controlling bugs exist...
