I think it was around 7 years ago when I read this particular manga in a manga shop. It was translated to Mandarin but I don't think there's an English version even now.

What's difficult finding the manga is that I don't remember the title and content. From what I remember, it has a very good drawing style (maybe something like GTO or Suzuka, the drawing is semi-realistic with a lot of shading), it's ecchi/seinen (nipples shown, maybe along the level of Sundome but again, I'm not sure) and the front cover shows a fish in a pot, probably being cooked (can't remember which volume).

I may be completely wrong about the fish/pot type and size, but I don't think there are too many manga with a fish on the cover. It may be a fishing or cooking manga, or it may be some totally random manga. The volume number is also unknown.

Reason for looking? Great art and ecchi. It seems that I've read just about all ecchi manga here, so I'm looking for something new. Perhaps one of these days I'm gonna have another look at the shop, though it's been so long the chances are super slim they still have it.

It'll be really great if anyone knows this manga. I'm not going to be optimistic though. Thanks in advance.

First off, I'm not sure on your manga. But is the fish/food/pot/whatever a photograph or drawn? There's a long-running cooking manga with photographs of food and ingredients on every cover. I've never read it, so I can't attest to any boobage, though.

I'm not 100% sure, but I'm almost positive it's a drawing.
