Turnoffs.

I hate spoilers. A story like this,
'Hana and Tao got an arrranged marriage? Will they fall in love??'
Well,I have to say a yes. This storyline isn't so unique anymore.  They're parent's have to set them up for an arranged marriage,In some sort of way. And they both hate each other,Then they'll slowly fall inlove right? I didn't even have to read a single line..

Too fancy letters... I sometimes don't know what you're actually typing.

'(Will be thinking later)' 
It makes me think that you're unprofessional. To me,You haven't really thought of the full plot,and just posted it up half-heartedly.  It would be alright if you change the tittle next time,But i won't really be interested in a (to be comming soon) story.

'Hana,(living with EXO) finds out that there's an anonymous lover? Among all of them that she's been living with for long?'. Long titles
First,You shoudln't introduce the main character in the tittle.  Second,There's a forward. So you don't need to put everything in the tittle. 

Last,But most important,BE CREEEATIVE!  Story tittles like,'Daenu is JYJ's lovers?' is a.. yes or no?
no. You know. 

Reminders; This is just my opinion,Your opinion may be different. so don't hate me.
