The author, judging by the text, one of his sisters is bis*xual, will Yuri be in this work? I hope not.
Even if Sam is part of the mc's harem, she will still sleep with Luna and with Lincoln, and also without Lincoln's presence. This is called polyamory, when two girls seem to be in the mc's harem, but they are also in a relationship with each other. This is not a harem. Anyway, I can't understand, Luna has been in love with her brother for 9 years, but she still started a relationship with a girl. It's kind of illogical.
