Do we like tsundere?
Don't bother. Tsundere haters have no idea what they're talking about when talking about 'tsunderes done right' or them being 'generic'. It's just a series of buzzwords they use to try and create shitstorms.

I'd prefer characters that are not modeled after any archetypes and have personalities that reflect some kind of original thought on the part of the author.
But if that's not possible, then yeah they're okay. At least they kind of resemble actual people, unlike the ones that don't say anything or the ones that can only blush and squeak out broken sentences.
She is perfect
Did HS, (or CR, whatever) sub all the bits and pieces that pop up in quick succession?
Mai waifu is a tsundere. Since when don't we love them anyways?
