When they added Ryo I thought they would go to the full harem (killing the possibility of a throuple) but I am happy she is just a side couple
Anyway... one more friend acquired. And the throuple is not in danger so it's all good.
The throuple is most obviously in danger of becoming a FFFMM polycule…
…or a FFFFM polycule (like in “
Kanojo mo Kanojo”, for example) if Ryo-san's “number one” ever becomes revealed as a
female otaku (and then Prestone here becomes forced to retype all these “he” into “she” for the new translation, uh).
Ryo-san has already said “Takuya is my number two” and “I kinda like the guy” (and even “if he happens to fall for me, that's not my fault”) and thus she's
this close to building her own reverse harem.
I can see that she still has her “number one” and her “number two” (unlike, for example, Amamiya Sayu who treats the Ijichi brothers equally), but that's just because the girl has her priorities. It does not automatically dismiss the possibility of a reverse harem.
Chat, is polygamy legal in Japan?
Kiryuu Shino (one of the central characters in “
Kanojo mo Kanojo”) once said that
there are numerous demerits of polygamy in Japan, not just being legally prohibited.
