Yup really like what you've done with Rukia. Yoruichi is great and all but a more down to earth girl has a lot of charm as well. I also like that Ohta seems to genuinely care about her feelings more than just wanting to screw her.
honestly I don't want rukia to be his romanctical partner, I'm against them being together.I will still read tho whatever happens.Cuz I love the story hehe,but rukia and ohta togther?Meh.
2-3 girls isn't a haram tho it would probably be hellish to get them to agree especially since they're both noble so he needs to have a lot a strength and charisma and most importantly lots of luck
