The show should be titled:
Monarch Legacy of Daddy
Because the show is literally about two grown adults who cannot stop bickering with a tag-along that behaves like a petulant child, with a dash of the rainbow stuff added in. It's a drama about Kaiju, yet where are the Kaiju? They appear for short moments here and there, then boom, gone like it never happened.
This drama went on the panderverse train to Family Court and never got off. A good series ruined, again.
