This game is perfect for those how enjoy obsessive, sadist, masochist and non-human characters. The only LI (Yui) is a yandere, a character how makes me want to learn more about his lore. 

The MC's name and pronoums are costumizable (He/Him, She/Her or They/Them). I loved this feature! There  few Visual Novels that allow fot adaptable pronoums. There is also an ending where you reciprocate Yui's feelings (the "good ending"). The game is excellent! I highly re comeend it and encourage you to follow the creator (he/him) on his other social media channels. He is attentive and caring toward his fans and his project.
