I don't think it was just to tease, although I don't think she's actually developing multiple personalities. My take on it is that her acting has become a part of who she is, so denying her acting is like denying her. (Rather than denying a separate personality.)
Very well said friend. Also, all fluffy ness aside, this panel makes one beautiful conclusion.
I have like big zero relationship experience. But, the way I see it, when youre in a relationship youre bound to see/experience all of your partner's sides or traits be it when theyre angry, upset, sad, happy, stressed, so on, so on. As for this series, its Rin being all of her other personas which I honestly think can be her actual traits as well. If you cant accept pretty much all of your significant other's sides or traits. I dont think you love her wholeheartedly. As in this series, its Eiji tried to only love "base" Rin, but not accepting Rin when shes feeling cheeky, cool, mature, or wanna be spoiled as his lover. Thats why she was upset, and I wholeheartedly believe she has all the rights in the world to. Thats why that panel makes a beautiful conclusion. He finally is willing to accept all of Rins sides as his lover.
Fluffing cute!
