I don't understand the people who are giving this a rate of "1" or "2" just because the story doesn't align with their set of principles and their real lifestyle preferences. Like can't you read the categories tags? If you want a fluffy sweet story go ahead and read those why are you here complaining?!!
Now about the story, LOVED IT! I just love any story that is unexpected and interesting, something that gets me lost in thoughts trying to figure out the characters feelings. This manga is easily in my top 10 reads and I will certainly read it again because honestly, one read is not enough to grasp everything going on in this story.
The twisted "love" of Hiroi for Take (I don't even think love is the right word here), I would like to know more about the basis of that and why it came to develop, The crooked "love" of Take for Hiroi, and his newly developed aggressive and obsessive "love" for Mine and how it grew and was scaled based on how much Mine loves Hiroi (or maybe it's not because of that and he hasn't figured it out yet??) Aaaah this is what I mean, I love this, it's very interesting, the feelings of these three in this story is something new, only few mangas covers such complex feelings and relationships. I don't understand how "Psychological" is not one of the listed genres here.
I like to think of the ending as an open one, cause there is NO WAY that this is the conclusion of these three's feelings, obsess and aggression mixed with love does not just simply settle, there would be surely interesting development in the future of their relationship, I hope there will be a squeal covering that (aside from the doujinshi series related to this which I am reading next)
As a conclusion, if you like interesting complex stories that makes you lost in thoughts and feelings, I highly recommend this one, it's amazing. But if you just want to read what makes you comfortable and what you're used to in real life, then avoid it and go read a cute comedy romance story instead.
