She didn't play with his feeling , she just want to make sure his feeling is the same as her ┑(￣Д ￣)┍
Yes
It's just my opinion
I think one of things that made this story stand out ( well at least for me) is how Adel was,her personality. She made the first move and then when the duke kept giving off "ehh I'm not sure about my feelings" vibe she didn't compromise with being in an unstable relationship. And when she had had enough of the Duke's indeficive ass she just said fuck it and left ( well as you know not really but technically she did) and when he finally got his shit together she accepted him.
I think so
I read a beautiful manhwa, i just annoyed when lady adele play tricks to duke felix. Seriously?? Duke felix is making his best to prove and protect her but she just played his feelings （/TДT)/ , but in the end it was a happy ending haha
