The story is about a dad (the MC) who just got divorced and his bond with his three adopted daughters, Abigail, Rebecca, and Lilith, who all have a thing for him, although Lilly starts off as a bit hateful. The girls are cute and have their own personalities, but the main character is a whole different story. It's fascinating to see how the characters grow and develop strong feelings for each other as the story unfolds, however... The real drama comes from the dad himself: his exaggerated sense of morality, or just his fear of admitting his true feelings, are what's standing in the way of any "inappropriate" relationship with his step-daughters.
In the never-ending and unbearable inner debates that the MC has with himself, he keeps saying the same stuff over and over: "this is fucked up, this is wrong, this isn't right, I shouldn't do this, what am I doing, I'm going to hell..., etc." It's like a broken record of guilt and regret that just goes on and on. Using guilt as a storytelling tool in an adult visual novel is just plain annoying and takes away from the enjoyment of reading it, a real kick in the balls.
This story drags on forever, throwing in some random and unappealing side-characters like Meiko (who's just poorly designed) and the lesbian duo: Beth and Vanessa, who honestly shouldn't be in the spotlight... but they do, and they all seem way too into the main character for no good reason, especially considering how dubious and indecisive he is. It's kinda annoying how the dev keeps dragging out the story with random side plots and extra characters that don't really add much, taking the spotlight away from the main love story with the three "daughters" and slowing down the progress of the plot, especially when it comes to the romance between the main character and Abby.
Even with all the flaws, if you can push through the cringeworthy moments brought on by the MC, there is some kind of reward. When he drops the act and gets real about his feelings, setting aside his "conscience" for a bit: the sexual scenes are the real treat in this visual novel – after hours of dense and repetitive dialogues and sick ramblings, it all leads to some seriously passionate sex sessions (those hotel nights with Rebecca and Lilith are memorable... take the blue pill!).
The graphics are decent with average visuals, not really feeling the devs' art style of big-eyed dolls, but you kinda get used to it. Abigail looks pretty good to me, her character is quite charming. So yeah, 'Single Again' isn't the top-tier visual novel I've come across, but it's not the worst either. Despite the main character and Meiko, there are some nice moments. Hopefully, the developer picks up the pace with the story and we finally get to see that long-awaited romance scenes with Abby.
