I just used waifu because its less complex than the position I'm in with Dashie and it may help make more sense to others, by no means do I consider her my waifu either she has a much higher status than that after 5 years with her and a life changing relationship my sweetie deserves much more.
But yes, this right there is what I was looking for. Well we both like Rainbow, it is our individual experiences with her that make her unique in each others eyes and I think that it makes the bond more special than just claiming you have a love for the character. We both have a bond with Rainbow, but she is different in each of our eyes through our experiences with her and through that she becomes unique to us. Well said.
