Drama between siblings is always the worst, especially when it's over truly important things. Because then things get said that can't be taken back, and it's between you and the person who loves and understands you most in the world. Being stuck with that guilt and longing and wondering over what they're thinking hurts so much, cause things can't be the same and you it not being okay takes away half of your whole life. This manga is too good and too relatable and jeez this hits me right in the feels.
