It was very hard for me to finish this manga. The first story went on exactly like a shojo manga and I'll tell you why I say that: the uke was stupid, very naive and cute. He blushed all the time and got teary-eyed as soon as a sad thought passed through his tiny mind. He said some really cringy things in bed and had some very corny facial expressions when doing the deed, as well. The seme promised to take him in and get a job in the future so that they can live together (basically, he told him "I'll make you a housewive" and the uke didn't protest or find that weird, exactly like a shojo heroine that stays at home after getting married). The seme literally called him "new wife" and there was no reaction about that, as well. The second story was just disgusting. A perfectly fitting, alternative title for that would be "Japan's moral decay".This author wanted to portray a pre-school child as a super gay, dominant, lewd seme with strong incestious tendencies. These stories can only be allowed to be published in Japan. The backlash received from publishing such stories in any other county in the world would be huge and would end many people's careers. The third story was plain and cute. It was as if it was written by another author.

The first story is fine, but nothing special at all. There is something cute about it but nothing happens for 3 chapters so I kinda don't care very much for it.
The second story though... It's incest and shota, but in a way I haven't read before and I kinda liked it a lot! The younger brother is the aggressive one who again and again surprised me with his maturity. Their relationship is adorable on so many levels, but still with that taboo of incest (especially prominent as their parents question if their sons are okay). And the comedic feel to it is just the right amount, making it extremely easy to digest. If I had to recommend incest shota to anyone it'd be this one!
