Ok, this may look like I´m obsessed! I´m not...really. I don´t even know why I wrote this! But I´m sure I´m not the first to do something like that and hopefully not the last. I simply like MerDer very much and they became my favourite TV screen couple very fast. English is not my first languague so I apologize for all mistakes and stupid sentences construction :D.
This wasn´t supposed to be like...scenes-related but then I couldn´t help it. I think that those moments between them are exactly what we like on MerDer.

So, why do we upendo MerDer? :D

Because addicted ones can find so many reasons.

Because they´re overrated but WHO CARES???!!!

Because meeting her in the bar changed his life.
Because Derek wanted Meredith to take advantage of him again.
Because of the line: „You´re an attending. And I´m your intern. Stop looking at me like that!“ „Like what?“ „Like you´ve seen me naked!“

Because when she learned that he was married, after a while she admitted that she couldn´t hate him and kissed him in front of the hospital.
Because, despite of how strange it could seem for Meredith´s personality, because he was her attending and she didn´t want to go out with him first, because he was married and broke her heart, she was the first to say „I upendo you“.
