If Nagi stays with his sister, it is still incest (even though they are not blood relatives) since they were raised as brothers and only discovered the truth little time ago.
The more I read the more it seems like an incest allowed, since Nagi and Erika are almost like their brothers
@MasterKurosawaKakeru unfortunately the translator said it would be deleted after two weeks, but the chapters keep coming out in Portuguese, only on another website and sometimes here.
The MC was unlucky ...
Those who didn't understand, the MC used the app to SIMULATE the dating with the girls, he didn't date them. It is not an NTR story!
So she wanted a sex friend and he wanted a serious relationship, it really wouldn't work
This simulation really scares me, because in the end the waitress did exactly as in the simulation, calling the MC to play with her.
