what a despicable onii-chan! he doesn't deserve the title onii-chan! 😡😡
everyone knows that it's a duty as an older brother to spoil and mating press their imouto!
Ah, the classic "if they're happy, I'm happy" coping mechanism.
DON'T LIE TO YOURSELF, you crazy little loli, YOU AIN'T HAPPY AND HE'S IGNORANT OF YOUR HEALTH
I will probably regret being semi-serious for even a moment about a manga like this, but I'd like to point out to everyone that she has no communicated the "love" for her brother to him in any way. You can't really blame someone for not reciprocating feelings they don't even know exist, especially since they're siblings so it's natural to assume they don't.
I feel like this is going to end in sewerslide. She's like one day from jumping in front of a passing Shinkansen, or giving her self the forever ceiling necktie.
