The first episode is adorable fun. The lead, T-Rex, is a cute puppy who sometimes reveals a little more manly side. He's knowledgeable about dinosaurs, knows what he likes, and seems comfortable being his quirky self. The female lead, BaiPlu, is more straight-laced and finds herself annoyed by this cute pup when he shows up at her house wanting to dig for fossils. A good set up episode, introducing all the main characters and quickly establishing the roles and relationships of the various players. A little stalkery to start, the doe-eyed innocence of the lead makes it cute and not creepy, and it's clear that BaiPlu is more annoyed than anything else.
All around enjoyable and I can't wait to watch more.
