It started with a joke, Their resemblance make them close together,

When marriage between husband and wife falls  

Jin is holding the necklace with a snowflake pendant that is hanging around her neck,  

I should be more careful involving my best friends in this mess that I created, I shouldn’t get in between their friendship and our relationship as best friends; and now I’m pregnant and I don’t know who’s the father between MinSeok and JongDae

He is still in love with her all this time; She is in love with him;

It’s just all coincidence,   I never expected to met him,
