Imouto no Mune ga Suki - Ch. 64.2 - A sister who has come to recognize her brother's scent

My disappointment is immeasurable and my day is ruined

Just keep the cute and familial relationship between them as it is, it would be so much better if the youngest one was just a wingman or something to the main ship and she was just treated like a normal little sister.
Their interactions are so cute already, I don’t want it to devolve into degeneracy like with the other girls
