When I first watch this part in episode 12, I had thought that perhaps this love note was written by Ma-Ji-ul. But on reading through it, I believe this should be from Oh Maria.
When detective Nam Gi Ri asked Ma-Ji-ul if the letter was hers, she did not show any recognition as she walked over to check it out. She seemed a little sad as she read it and then taped it back onto the board. Even though it’s signed off with a nickname, she would know who had written it.
You might not know, but I like you.
I’m telling you in every way possible except through words …..
But you’re absorbed in the Gapdong investigation, so how could you notice that?
Love at this time could be a luxury
But still …… love helps me get through this difficult time
I’ll see you later ….. crybaby ….
