this is why i dislike childhood friends. it's their own fault they loseGirl, you made your own mess, and you had your entire life (up to the manga’s start) to fix it.
it's pretty obvious that his imouto wants his dick
It's pretty obvious
I'm not sure she likes him... yet. I think it may go 2 ways, she keeps acting until it becomes real or she didn't realize it was love until it's too late. Generally the plain joke or pride stuff doesn't last long, but I might be wrong.I wonder if the childhood friend actually likes him, or if it's like... a matter of pride or something. She's always had the leg up on and has been able to mess with him, but now it's clearly not having the same effect on him. So in order to sustain the dynamic they've had for so long, she feels the need to escalate.
Iunno, the "childhood friend has a crush" just feels out of step with this manga's style.
