Gareth isn't one of my favorite male leads, but I definitely don't hate him. Mostly, he is just frustrated with Hyacinth's apparent lack of consideration for her own safety. He grows as a character though which was good.
I find I see a lot of myself in Hyacinth. She's smart and straightforward and she knows exactly who she is. She owns up to it. I wish I pulled it off the same way. Loved it:)
