<p>Out of the <a href="http://www.mangaupdates.com/series.html?category=Personality%20Change/s&amp;filter=oneshots" rel="nofollow">five</a> I've found, this one fits the closest:</p>

<p><strong>Blackberry</strong></p>

<blockquote>
  <p>Ever since Fune Momohara was told that she was just like a "guy
  friend" by the boy she liked, she's been bent on becoming the ideal
  girl. But when she meets the perfect guy who turns out to be more than
  a little pretentious, she realizes that it can be difficult to keep up
  appearances!</p>

<p>I haven't finished this yet, but it might be S+M, however it doesn't mention anything about nighttime:</p>

<blockquote>
  <p>The first man who doesn't obsess over her assets turns out to be the first man she ever wants to have obsess over her, though there's something strange about him... One time she's with him, he's a sweet masochist, the next time he's a bold sadist. Which does Ryou like better? The S or the M? She'll have to make a choice, because it turns out that she CAN'T have both. </p>
</blockquote>

It is a series, not a one-shot.

<p>A friend of mine was desperate to find this manga... after so long trying to find, she finally found! She said it's an extra chapter of <a href="http://myanimelist.net/manga/3457/Ookami_Nanka_Kowakunai!" rel="nofollow">Ookami Nanka Kowakunai!?</a> If anybody else is after that, it's here :) </p>

Can you provide at least some evidence to your words, like a description from anime database site or wikipedia?

<p>I was trying to recalled and find some manga that I have previously read before I stumbled upon your question. So it was not until that I ultimately found the manga that I have been looking for, that at the same, I found a manga that seems to match your description. </p>

<p>Here it is: <a href="http://myanimelist.net/manga/39673/Saitei_na_Hito_wo_Suki_ni_Narimashita" rel="nofollow">Saitei na Hito wo Suki ni Narimashita</a></p>

<blockquote>
  <p>Liking the worst possible person...... "If you love me, you will fufil my wish, right?"
  Yui confesses her love to Hiro who hides a dark personality...</p>
</blockquote>

<p>I haven't read it before but by the looks of it, it's maybe the one.
Hope it helps!</p>

<p>I read a manga a while ago about a girl who fell in love with a guy whose other darker personality appears at night. Later on, the girl and the dark side fell in love with each other and the dark side got jealous that the girl likes the other side of him more.</p>

<p>Can anyone identify what this manga is?</p>

There are likely to be a lot of oneshots the fit the bill. Can you be a bit more specific as to the outlying plot, characters features, or drawing style?

That looks like [D.N.Angel](http://en.wikipedia.org/wiki/D.N.Angel) to me. Though I'm not too sure as the plot could be any story nowadays.
