I'm glad Sam Dal and her family (specifically her mother) had some character development through the past couple of epsiodes because they were so loud and stubborn the first few episodes and I really disliked that tbh
I got second lead syndrome from the ML himself (past self). I do understand FL already fell in love with present Tae Ha and not the past. Still, I was wondering IF they'd just live in Joseon happily and then in another life they (FL and ML) would be reincarnated and fall in love.
