Hmm If that what you mean, if we look back this author not trully care about that thing detail. And now almost 98% what we want to know about Rika has been revealed.Not what i meant, actually. I meant that she omitted Misato( who was the reason she started dating Iwabuchi to begin with) and Shiratori( who admitted he did not sleep with her, but said she was somewhat famous on the Ura Aka scene) from her account.
This chapter really reinforced what i wanted to convey: that Rika showed a very "moe-moe-kyun" personality, only caring about her love plan, but omitting the nuances around it, all in which she's a cold, ruthless manipulator. This is exactly the missing piece we're after.
But man... i think, after this trouble she is will be not fooling around again. But when she push Sousuke to bed and said i love you ilove you so much she also told she will always love him even after giving birth and embraced with another man, so that mean even after this she will be sleep with other men again, she can't be helped. Author trully made Rika how bad possible in the end. I trully curious how Rika will be excuted to made this series has satisfying ending.
