I read Chintsubu and I would like to read another yaoi with a couple like Iwabuchi and Kamiya. the uke is tsundere(!), easy-going, slutty, but always embarassed in a cute way. And GAY. And the seme isn't possessive, but likes the uke and he never ever rapes the uke or is angry with him, is sweet and CARING. Actually doesn't have to be yaoi, shounen-ai is fine. thanks.

You know, because when I see a tsundere uke, the seme always seems to rape him.

AND
do you know of any yaoi/shonen-ai where both guys are tsundere 😕

if there is an option between "to do" and "not to do", I will always choose the latter.

Maybe you can try Yasashii Ryuu no Koroshikata. It's not Yaoi, just downright shounen-ai. 😀
The uke is a tsundere but he's polite so it's not very obvious. and the Seme is really SUPER sweet and so caring.
Just a heads-up, the series has not been completely scanlated yet, though it is complete.

Oh and, I don't know any yaoi/shonen-ai where both guys are tsundere 😐 I always come across series/oneshot where the seme is crazy in love with the uke 😛

thanks, I'm going to wait for the scanlations, though, I read only completed series 🙂

Another manga like that came to my mind. the second couple in Welcome to the chemistry lab was like that I think.

if there is an option between "to do" and "not to do", I will always choose the latter.
