He might not want his sister to butt into his relationship but he doesn’t want her to be completely indifferent to it. Can’t wait till he formally introduces her to the family.
She was dumb for even considering that a girl that was on a video call in her pajamas in the dead of night with him wasn't at least pretending to be into him.
I was on the edge of my seat. I'm not the kind of dude, and yes hate me if you must, to despise incest. I've come to accept siscons and brocons over the years of reading mangas. So, in case the sister did come to have feelings for Ichikawa. I'd be embarrassed, a bit depressed, and definitely a lot more frustrated. Thank god it turned out to be her just looking after Ichikawa. I knew she was an amazing sis!
The moment you realize she DIDN'T tease her lil' bro cause she thought he was being played, and that would've been cruel.
But when she finds out Yamada went for a sick visit of her own volition? Boy, it's ON! 😂
I was totally expecting big sis to immediately take up that annoying-sister-teasing-her-sibling-who-is-in-love trope, but that subdued reaction at first threw me for a loop.
She made damn sure there was some chemistry in this pairing before stoking the fire...
