Imouto no Mune ga Suki - Ch. 59 - My sister wants attention

[colorlesseatstomboys]

The problem there is, once you go looking over things, the faceless guy's general design is reused a lot. If they really are the same dude, he's got an utterly insane amount of sisters. Orange hair, both older and younger, green hair, blue hair, blondes, and so on. Also Pokemon.
These two pink haired sisters and the loli at least have all appeared together with the same brother to be certain.

Yeah just rechecked the hair. This guy is different from the usual MC with pink haired sisters.
So no one-chan for him 😭
