So, like it is said on the title, looking for tsundere male lead. 🙁 Romance genre is required. No yaoi or shounen ai please. Thank you for your recommendations!!! 😃

You've probably read some of these, but...
Fukumenkei Noise
Ginzatoushi to Kuro no Yousei - Sugar Apple Fairytale
Hana yori Dango
Himegimi to Sanbiki no Kemono
Hirunaka no Ryuusei
Nakanmon!
Nousatsu Junkie
SA

Thank you for the suggestions! But, yeah, I've read these. 🙁 It's so hard to find in the tag because it's mostly yaoi or shounen ai. Again, thank you!

Try an "Advanced Search by Genre": [url]http://www.mangaupdates.com/series.html?act=genresearch[/url]. You can require some genres and exclude ones you don't want. There's a spot for tags and you can "Only show manga not on any of my lists".
