I'm a sucker for this kind of game "Living together/Cohabitation". But GOD, the story and the characters were written by an incel, and you see it with every fucking sentence. You can found every dumb shit incel believe.
The female boss, Peggy, who is of course a bitch, because all women with a little power bully all men under them and are more terrible that 99% of all male boss, but she has the body shape of a woman in a hentai, so big boobs, big ass and a pretty face. Of course, she seduces and sleep with her big boss to get her job. She's manipulative, a liar and insult and demeans her male coworker every time she opens her mouth.
The succubus... Succubus are the hentai equivalent of slime in RPG. The level 0 of creativity. She's the same archetype of a succubus you can found in a hentai. She loves sex, human male, big cock and will do every thing that is related with sex, cock and sperm. The only thing that she know is pleasure and especially giving pleasure to men because that's her only reason of living... Really level 0 of creativity.
The MC is your typical pathetic hentai MC with a huge cock. You can literally resume the MC with this sentence "I have a miserable life, women are belittling me, and I have no friend, oh GOD of all incels have pity on me and give me fine women who will jerk me off, be my little slut, sex slave, mommy, maid, punching ball, stress relief. ". A pathetic man with a huge cock that serves him for nothing. Really why are this kind of MC don't work as a pornstar if they are so pride of their humungus cock instead of whining and saying all women are slut, and they don't love him. Oh... And of course he is a rapist, like 99% of males in hentai.
TLDR : it's an incel game with good esthetic and animation.
