Was a bit turned off buy the art style, but glad I read it. Great natural dialogue. It reminds me of my relationship with my gf.
Can't seem to find that "falling out of love" part the title mentions.
I interpreted the "falling in and out of love" to refer to how the blonde one usually comes across nonchalant which causes lulls in their relationship, but then she also does cute things which causes the other to fall back in love with her all over again.
But I need to say, who falls in and out of roller-coasters? That sounds very dangerous.
It's probably referring to the ups and downs of a rollercoaster lol.
