What a shit show. No character depths. No properly explained motives behind any characters. No proper story line. Porn without plot would have been better. Waste of the good drawing styles. I can't imagine someone writing this idea down and then adapting it to a manhwa said, you know what ok let's do this. And then the editor said yeah it looks fine. And then they actually did it. The story really sucks, they could use the non-related brothers troupe but could do it just this badly.
It hits better after you know how well Akito is scared of losing Sana to her giving birth to their babies because his own mother died during his birth and it's his biggest trauma to be always feeling guilty and accepting pain all his life to perform normally because he thinks that is to only way to pay off his sin of killing his mother EVEN after everything they go through to change that perception he has. And at the same time Sana was abandoned as a newborn baby and she always grew up with a fear of abandonment+ losing her father in the anime(although it's different in the manga) and she said to her biological mother that she is grateful to be born because if she was aborted as an unwanted child she just wouldn't exist and that possibility scares her to the point of trembling. So she would never do that to her own child she is pregnant with but at the same time Akito just cannot stand the pain and triggered traumas being with Sana causes him after living with the guilt of 'killing' her mother in birth. Although it really didn't have to be this messy in writing, with Akito abandoning Sana and all. But I just assume that's because it's a crossover and more attention is on the both female leads rather than the other characters and that's also why Naozumi was just merely mentioned. Overall I would give the whole series a big 8/10 because it was so fun and emotionally engaging at the same time! (Except the fact that Sana is born out of her mother's relationship (?) with her uncle at age 12 which makes her give birth to Sana in a bathtub at age 13(excuse me what da actual fu-) and abandon her in a park and still claiming to have really loved and cherished Sana's father(greatuncle) and yet getting slapped for it by Sana's legal mother for abandoning a baby DESPITE being an assaulted and abused child herself)
