@Someone2Love There's a reason step-siblings are so popular among incest romances. You get the tension of a taboo relationship without the ickiness of a blood relationship. Ignoring the fact she's redoing this a second time, they're basically strangers who met because his middle-aged dad decided to marry a teen shortly before he kicked the bucket. She's his mother in name and the eyes of the law only. You couldn't ask for a more perfect setup for this kind of series.
Anyway, I'm just observing the trend so far. If there's another Romeo, he hasn't appeared yet.

I agree that it's weird. But like it was mentioned, they're like two years apart. So it's this weird situation where position wise, it's utterly weird but in terms of general relationship potential (I can't find the right word for it) such as age, compatibility, chemistry, it's very normal. Not only that, it seems to imply that she never had any sort of physical relationship with her husband (he literally married her due to potential skills to protect his family and now as an actual wife), so it won't be weird either in that aspect.
Basically, it's a weird situation and I don't know whether to root for it or not. If they go for it, I'm fine with it. If they don't go for it, I'm fine with it and is understandable.
To anyone curious of the ML and what he looks like...
Refer to the cover image of this manga. He's the guy with black hair & blue eyes. His name is Nora and his father is the man who helped Suri on chapter 5
