I dont wanna leave spoiler but your confusion will be explained on the following chapters sooooo u can continue reading it hehe
if im not wrong , haejoo noona is not really his sister. she's adopted by yuri's family.
I see. This is gonna be interesting. Thanks guys! ~_^
the sister he likes is actually not her biological sister, (she's adopted) but there's a whole chapter or two that goes into detail!!!
I'm still on chapter 6 but I'm kinda confused about Yuri and Heejoo Noona's relationship. So does Yuri has a crush on his sister Haejoo? I mean they're siblings right? And he has a crush on his sister? How does that happen? Will it be explained later as soon as I continue to the following chapters?
