The ending was very satisfying. Is really episode 45 the final episode? If it's the final episode have season 2 of love designer there are some part in the opening that wasn't seen in the episodes please have season 2 please or another episode more episodes. There are some part of the story that was left blank. We still have a questions like is the company of song Lin will be known? Are they going to have a baby?
