Lol I've just watched the first 2 episodes of Acchi Kocchi and the tsundere in it is fine!!
I can accept this because all tsunderish physical actions are totally not portrayed seriously, and nothing ever happens to characters at the receiving end, not even a scratch. This, I am fine with.
(This show strongly reminds me of Hidamari Sketch though.)
Overall this anime is good for some mindless, nonsensical enjoyment.
By the way I need more good romance anime though. I don't mind if there're harem or ecchi in them, but preferably those with a more girl-loves-guy situations, be it the girl confesses first, or the girl does lots of things for the guy, or the guy is just dense, or whatever. Harem shows are usually like this, but if it's not harem (just one girl is involved in the relationship) then it's even better.
Thanks!
