I just finished "Love Design" and I have some thoughts. Minor spoilers ahead ...
Love Design is an easy to watch, cute, fun and low angst rom-com. Although there was nothing especially innovative about this drama, I really did enjoy it. It stuck pretty closely to a standard fluffy rom-com template, but the story was entertaining, the production was excellent and the acting was better than you will see in many Thai GLs. I especially enjoyed Jane Methika Jiranorraphat's acting. She absolutely nailed the determined, but slightly goofy character of Rin, and her flirting with Aokbab really was fun to watch.
Having only 8 episodes resulted in a focussed narrative that didn't drag and wasn't padded with unnecessary subplots and characters. I also appreciate the fact that the character of Mind earned her redemption, something that most drama writers forget about when "forgiving" evil characters.
An absolute must watch for Thai GL fans, and also recommended for any fan of fluffy rom-coms. I'm looking forward to the special episode which is being released soon.
