Couples Who Have More Chemistry Than the Main Couple

I've been planning on writing this ever since I finished Bridal Mask, so it's pretty overdue, but here goes:

There are so many cases when the main couple just doesn't have the chemistry we'd like.  Or even if they have decent chemistry they get upstaged by the side couple, or a couple that is completely non-existent in terms of that particular drama (but those actors better start dating in real life).  Secondary romances get us through many a melodrama, and quite often upstage the main romance all together.

I know my OTP is often not the main couple, even if I like them too.  So here are some real OTPs, or at least some couples with more chemistry than the main couple.

80. Inborn Pair 真愛找麻煩 (2011-2012) Taiwanese

Chris Wang, Annie Chen, Xie Kun Da, Puff Guo, Chris Wu

Drama Rating: 6/10     Neck Score: A

Another one of those super long (like 84 episode) dramas that make me wonder why I started them but really love in spite of that.  Annie Chen is still studying to pass the bar exam (she has the worst luck) and Chris Wang is the CEO of a zoo resort.  The have a chance encounter that makes him thing she's a home wrecker and she thinks he's a cheater.  Then they run into each other at the temple, where they get the fame fortune.  Then the grandmother (my favorite Taiwanese baby hungry grandmother- the same one as in Love Around) finds out that she is the girl that she promised would marry her grandson because Annie's grandfather saved her family's life when both Chris and Annie were in the womb.  The grandma then does everything she can to force that promise's fulfillment, even pretending she has cancer.  So the couple, even though they started out hating each other, decides to have a secret contract marriage to make the grandmother happy.  Then lots of crap happens.  Annie has a short temper, Chris has a girl who is totes in love with him and not willing to let him go, Annie's first love shows back up, and there is pressure to have a baby, etc.  They are also both really stupid and won't admit they like each other when they clearly do.  Also, there is the other sibling drama.  The older sister is so dumb and controlling that she basically sets herself up to be cheated on by being too willful.  The younger brother is a horrible ladies man, but he meets his match when the girl he picked on in kindergarten comes back for revenge.  So in spite of all the craziness, and long running series, it is actually pretty enjoyable.  I hated the other girl, and his mom, and the cheating husband crap, but the main couple (Annie and Chris) and little brother couple (Kun Da and Puff Guo) are super compelling and I loved it.  I've loved Puff since Just You, and this is further proof that she is a great actress, because her character is so different in this one.  She is a calm, well mannered, yet revenge seeking/man training girl with a cool gangster background.  Yes.  Even though this show was silly, I still liked it.
