Even the translations are spot on. they are purposely done. Kuroh saying "stigma" is actually part of the story and surprisingly not a typo. as perceptive as MC is, he's literally trapped so he cant do much. I guess whatever happens...Makoto is the hero of the story now. Yes hero. not heroine. She's however, slower and less perceptive than the MC. its gonna be awhile before she realizes things. She's still at the stage of blindly supporting Takako's relationship with him, while hiding her feelings for Rin.
