Exactly lol, harmless picking on is fine, but it makes the relationship better that they love eachother first rather then hsting eachothers guts
I'm just thankful it's not yet another failed garbage tsundere... it's so rare people do a tsundere that isn't genuinely outright insufferable lol and it seems to constantly be a sister character that ends up being the tsundere that just constantly argues and fights with the MC. Over used trope + poorly used trope combo makes it so bad. Now I do have to say, I can enjoy a brat and a well done tsundere that isn't souly there to just be annoying. But gods am I thankful Ash is a damn good sister type instead of a garbage tsundere.
