Far Away Love (2016)

Rich guy, poor girl. Guy relentlessly pursues the girl and lets no one at all bully her - no matter who they are. He's totally in love and acts like it. Guy owns a business too and girl works for him. Lovely friendships in both dramas.

Basically the same plot : rich guy/poor girl. The main character in this both dramas is a single mother trying to do anything for his child.

Both have a rich guy and poorer woman who seem to dog each other's footsteps with off the cuff meetings that end in (or are caused by) misunderstandings.
