Totally agree with you !
Nabi jumped into this relationship of her own free will. Her attempt to get the answer she was hoping for was quite weak.
It looks like he has evolved and wants more than at the beginning but she is the one running away just when he realises his feelings . She is a mess because of her ex OK but her childhood friend is NOT the solution to her frustrations . Great guy but childhood friend - only- She is still attracted to Jae Eon and only to him.
In ep 9 Jae Eon he argues with her as he feels he might loose her . It is their first real fight. It is time for Nabi to face it ! She can't just run away. She got to deal with it. After all they have a lot in common as artists. And obvious great chemistry which Sol underlined so well by saying " it is a miracle" that kind of attraction/passion.
Nabi don't use your childhood friend ...as you already expressed why you can't be with him. Be honest with him.
And be honest with Jae Eon. Take the time to discuss everything. Pride is in the way.
Lots of people label the relationship toxic. It is not justified . It needs to mature no doubt to survive... but has potential. Anyway running away as she seems to want to do is not a healing step. She seems really hurt .
Processing it by talking to friends like Sol might help - if she listens...
Love this series ...
Curious about ep 10 !!!
