I’ve never thought too hard about てもeven if before, but a simple translation feels strange. So obviously there’s more to think about here.

てもeven if is literally て(connection particle) + もalso, て(connection particle) being a connection particle like “and” or “so”, and も being an inclusive particle like “also”.

If you just use て(connection particle) on it’s own, you get something like a command.

窓まどを開あけてOpen the window

• Literally: Open the window.
• Natural: Open the window.

Let’s put いい after it, so that we can root the rest of this text in a really well known construct, ていい(continuation) is good/てもいい(continuation) is also good.

窓まどを開あけていいIt'd be good if you opened the window

• Literally: Open the window and it’ll be good.
• Natural: It’d be good if you open the window.

Seems kind of pushy, maybe in casual conversation it’d be okay? If you add a bit of an uncertain tone (represented here with a ?), then it could be seen as a casual question.

窓まどを開あけていい？Would it be good to open the window?

• Literally: Open the window and would it be good?
• Natural: Would it be good to open the window?

So, what does てもeven if mean? Well, it shows contrast to the expectation. This is why we translate it as “even if”. It’s also why it’s considered more polite to ask a question in this manner, we are showing contrast to our actions.

窓まどを開あけてもいい？May I open the window?

• Very Literally: (Even though I think it’d be bad), if I opened the window would it actually be good?
• Natural: May I open the window?

That brings us back to そんなんゆーてもeven if you say such a thing. With this context, we can see that we are talking about someone saying “such a thing”, and contrast to their expectation of having said it. (The unexpected contrast remains unstated.)

I asked a friend about this title, and she estimated that the meaning here is something like そんな風かぜににせものって言いわれても困こまるI don't like it when people call me fake like that.. The unstated part is that they’re a little annoyed despite the contrary to the expectation that they maybe wouldn’t be annoyed.

• そんな風かぜにIn a manner like that = In a manner like that
• にせものって言いわれるto be called fake = to be called fake
• てもeven if = even if / contrary to what you may expect / despite / and also
• 困こまるit bothers me = it bothers me / annoys me / makes me angry

This is kind of like how in Japanese when you don’t like something you don’t explicitly say it, you kind of just trail off: これはちょっと…This is a bit... (This is a bit…).

Much like てもいい(continuation) is also good, I think the implied meaning here is to soften the assertion that what was said (“such a thing”) was wrong or bad or that they didn’t like it. So a more blunt translation might be “Don’t call me that!”.

The best native translation I can muster is “Regardless of how you say it”. It’s not actually what’s being said here, but it makes me think that we are implying something is wrong with what they said or how they said it, despite the expectation to the contrary, without explicitly saying it.

So I’m going to go with that for now, but I may change my mind later.
