I felt Rika was emotionally abusive to Kanji. She never called me by his name and dismissed his complaint about it.
Of course, the free-spirited Rika was a facade but still a lovely character with a good heart.
The kind of girl to admire from afar but a horrible girlfriend.
It is like dating a female boxer. You can admire her knocking people out in the ring when its you and her in the ring,
that's something to dread lol.
Rika is very similar to Riko from My Sassy Girl.
Even the phrases they use are verbatim sometimes eg:
'Never in a million years'
'I am not telling you'
' I don't need a dream, I need you'
She pushed Kanji away so many times but was sad when he left her.
Did we ever see Rika's house? I think it showed how closed off she was emotionally

A running theme was also her running away from him. He kept chasing her so much that he didn't know if she loved him
She was both free spirited and clingy. And taking a closer look, you find out the harsh words that she said to Kanji were actually rebuking herself. She seemed to be rebuking him for being clingy but she was rebuking her clingy self.
I think the reason why I love Rika so much is that she is a hypocrite.
It made her beautifully flawed.
