Did you read the manga? Yona did not had her revenge on Soowon early on the series because she realized that there's something more important which is to protect her country and do what her dad couldn't
And a revolution would not be good because the kingdom is already target of other countries, so it's like a double kill for her people if she decided to rule
And more important I hate Soowon but he is a good king and Yona knows that and that's why she cannot kill him
You guys do not get Yona and Zeno at all
He keeps yapping about how ignorant she is and how he loves her WELL WHY DIDN'T YOU THINK OF TELLING HER WHAT THE REAL WORLD IS THEN IF YOU LOVE HER THAT MUCH
I understand the fact that he was in a difficult position because she's still the daughter of the person he wants to kill but his actions don't make sense







Honestly I just want them to remain friends
