Liked him in "I Really Really Like You", became my secret obsession in "A Good Day To Have an Affair", fell in love with him in "Chilling Romance", and became his fangirl in "Shut Up: Flower Boy Band"... yup! ;)
Okay, so I'll explain the end as how I saw it.... I'll reply to this so I can mark it as a spoiler ^^
When Julian gets stabbed, he dies. Then you see her house looks abandoned and she is getting ready to leave, this tells she's going somewhere and not coming back. As she's getting ready, you see she has recovered her eyesight so it makes you believe that her operation went well, but she looks like she isn't suffering at all... you know since she's alone. Then you are met with a snowy and bright scenery and she's walking through it with no bags (remember, it looked like she's leaving her house forever). Then she sees a big tree right in that snow white scenery and walks to it. she meets Julian as she gets near the tree. Okay, so... She died as well. She's on her way to heaven when she's met by Julian; He's been waiting for her ^^ they get their happily ever after in heaven~
what happen in the end? yaah i know she knew that he's not her brother .. but did he died ??
Yes, I do believe they both died. Her house was abandoned and she looked great like nothing's wrong and then he looked great also. plus the snowy scenery and that big tree? Yup, they both died and are in heaven.
So at the end does she never realize that he's Julian and not her brother? Are they meeting in heaven at the end?
Yes, since she heard the conversations she realized he isn't her brother (but still wanted to trust that he isnt with her for her money since she loves him) and in the end I do believe they end up meeting in heaven.
Who did she play in My Little Bride? I just watched it last week, and I don't remember her 14 year old self anywhere?
The main girl's friend, the one that got mad at her since she liked the baseball player guy too. Then she forgave her and told her she must be lesbian since she likes her friend more than a boy ^^
