Both the couples meet when they seat in adjacent tables alone in a restaurant and they sit together to save table space. In both dramas the FL is still in love with her ex and the ML is younger.

Both have Ruby Lin working in the entertainment industry falling in love with a younger man. In Drama go go go, she plays a naive , timid script writer who likes a younger actor, in My Dear Boy, she plays a confident, successful movie director falling in love with a technician. I recommend My Dear boy.
