I think the writer was confused till the end... i mean, if he wanted to pair up haneoreum and kang, he shouldn't have paid so much focus on the relationship between haneoreum and namjin. Like all the episodes were basically the building of relationship between haneoreum and namjin until suddenly she get distracted during the scheduled marriage proposal. He should have focused on how haneurom and kang were regaining their lost love. The main purpose or motive of the drama was unclear. But still the drama showed some unlikable reality.. so it was satisfactory.
