On page 5, Rino tacitly admits she had sex with Kounosuke's
father, without crudely spelling it out. Like all good secretaries,
she's also a good diplomat.
This could be a significant plot point which, IIRC, Kounosuke almost raised in Chapter 1 as one of the reasons why at this point in time he wanted nothing to do with his father or his company. But I'll be content to let the artist develop that at his own pace.
@H-Connoisseur Normally, I do think that a guy, or gal for that matter, shouldn't be influenced by their partner's past if it's just that, their past. Now if those attributes of their life still influences their lifestyle presently or more importantly, will influence the future, then that's another story. That might apply to Kounosuke's situation. And also...if that past hits home in a personal way like, say, having contact with the homewrecker that wrecked that person's home (i.e. you suspecting that you're screwing the person that made your parents get a divorce), that's a past that can't be overlooked imo.
Well if the father is still married to the mom, or if they separated bc the father could not stay faithful, I definitely can see why Kounosuke would have some resentment toward his father and the company.
I like my mind wondering into my own imagination, so when I do that with this story, I ask the question "How did Kounosuke's father meet Rino?" Was it something similar to a "Pretty Woman" scenario where he paid for a hooker - maybe in this case he took a liking to her instead of falling in love with her and offered her a job as his secretary? Maybe the next chapter offers some background to her history working at the company.
Superb Combo exhibited by Rino-san (in no specific order): (1) Office Lady, (2) Sexy Onee-San, and (3) Possible Dominatrix (certain dialogue from Chapter 1 implies it).
That list of prospects may get the harem train going, but it probably won't do the MC any good ..... cause once he's had Rino-san, any other woman just won't satisfy him - even the "femdom" sequences.
