I mean it makes sense, she is questioning if Aya likes her or the made up Onii-san fantasyWhat the f. I did not expect for her to have herself as her romantic rival. A literal love triangle between her, her other self, and Oosawa. This is Miraculous Ladybug levels of absurd.
Yeah, sure, but it's funnier to make fun of her for fearing being NTR-d by herself.I mean it makes sense, she is questioning if Aya likes her or the made up Onii-san fantasy
She knew it right from chapter 1.So Mitsuki is aware that Oosawa has a crush on her (cool side)
