You meant Akatsuki no Yona/ Yona of the Dawn right? I love that manga to bits and think Yona is a great character too. I do agree it seems a bit fast here but maybe some time has passed? Or she could be susceptible to falling for pretty faces which isn't a great trait to have ^^'''' plus I want to see her other options before she decides to settle for this guy who was just kind to her, that seems a bit..lazy and not a good idea in my opinion
