Help! MDL citizens. The K-Drama I'm trying to find the name of has the following story points:

Middle-Aged Married Woman working as a housekeeper. She was working at a publishing agency but had her work plagiarized by a co-worker. She is caught stalking the former co-worker online. Her Mother-In-Law finds the police notice accusing her of the cyber-staking. Her husband is rather clueless and blames her sadness the miscarriage and possible menopause.

 Handsome Young Man who works as a 'Gigolo' meets this Middle-Aged Married Woman  on a bus and gives her a very expensive scarf gifted to him by one of his 'female clients' because she is cryingThis Handsome Young Man has attended the funeral of his friend/co-worker who committed suicide. He assists in burying his friend's ashes by a tree. Later he tries to give some of the ashes to his friend's sister, to get some money.  

Middle-Aged Married Woman meets with her father who collects cardboard boxes for recycling money. They talk about her sadness.

Any clues. All help is truly appreciated.

This is most definitely Lost

K-Drama "Lost". Outstanding!!!
