The objective of his post is to clarify some things about DaraHae. The deluded shippers believe what they want after that. 

It's ok if you ship two people together because you think they are cute together (even further if they are both your bias), what is not so ok is invent some "s" to make it seem like they like each other just to feed your ship =.= The idea is to ship just because it's fun but be careful not to mislead people.

I'll give some examples of I've ever seen:

- Say that Thunder (Dara's brother) said in an interview that Hae was courting Dara (even if Donghae was, you think that Thunder would say such a thing in an interview? Dude, idols dating someone is like a taboo in korea = . =)

- Say that Hae was in Big Bang´s concert just to see Dara (who had come to see the concert), when BabyHae was not even in the country at that time. (if wasnt a concert was something similar, but I remember that Hae wasnt in Korea at that time.)

- Relative about messages exchanged between them on twitter, I regret to inform but a man and a woman can be friends without second intentions. I really dont understand when a man and a woman talk to each other or have a meeting, why  people just automatically think they are interested in each other and that they are dating?

- Stop trying to see coded messages in everywhere. Like, she tweeted, "Do you love me?" because it was the title of 2ne1´s song that were promoting at the time. And Donghae tweeted "I Do… Thank you Thai ELF!" due to the project that Thai fans make because of Suju´s song "Marry U".

In relation to the photo above, I read this in a comment from someone on allkpop

"…. actually the girl he was talking about in strong heart was introduced to him by TVXQ Yunho, he asked Yunho for her number and he gave him and they start to know each other… but the girl betrayed him because she was dating a guy who was studying abroad and if her boyfriend will come she will go hang out with him and stop contacting donghae if he goes back to studying she would contact him again. donghae knew what was happening, and he still likes her.. when she was getting ready for college entrance exams, he would bring her thermos bottles and fruit, at the end the girl was tired of his 2-year crush on her, she told him 'You can go now' and she wanted them to separate. After 3 months of their separate she called him crying and she told him how she remembers how well donghae treated her and wanted to meet him again donghae said in that moment he wanted to be a bad guy.. because he was thinking that women like bad guys since he have been continuously dumped by women, he thought of becoming a bad boy. donghae said he have expressed his unrequited love with her for 2 years, but she never received his love. he was so worn out. he spent his days with the lights off hating the world. Soon, she called and told him she missed how well he treated her and wanted to start a relationship with him." and he said yes… he wanted to be like her  he wanted to treat her like she did with him.. he wanted to treat her badly  so he date her fo a moth. and the nickname "man number three" which the SJ members was calling him during WGM was because he appear on a show name "Star Affection Village" .

Edit: if you don´t believe, you guys can also see/read a old news from allkpop: Donghae reveals the story of his past crush on 'Strong Heart'

So this girl is a with a big B. Believe me, you dont want this story to be about Dara.

Go see for yourselves the episode where Hae appear and draw your own conclusions. 

I've seen people in that post saying that "it just for fun"

But what's the point now if you guys only clarifies it after a lot of ingenuous fans who believe everything that appears on the Internet without question, have already read that and have created a whole story in their heads of how Donghae and Dara are dating and will marry and have a lot of babies.

- Same with D&E's song "10 years"

As you can see in this post Donghae didnt write this song so stop deceiving people by saying that he wrote and that music is for Dara.

- And DH (initials which he put in the text with the photo) means DongHae, not DaraHae.

- And finally: because of Suju M´s comeback i also seen people comment that they expected that Suju-M and 2NE1 promote together for there to be DaraHae´s interaction. 

But you guys are really Super Junior and Donghae´s fans? Like, isnt Super Junior´s comeback, but is their sub-group, Super Junior-M (Mandarin), that mean, that comeback is happening in China/Taiwan,… Has no way 2ne1 and super junior m promote and interact because they are in different countries lol

Okay all right. Past few days it was confirmed that SUJU-M would also was going promote the song in Korea but I've seen people saying this before they have even confirmed that there would be promotions in Korea. And I was like: WTF?!

And For God, they just take a picture together. How does that prove that they are dating? 

To me they are just friends. I don't understand. 

Don't you guys take pictures with your friends? If you take, this makes you guys are dating each other?

To me it is ok ship them but please limit yourself to the truth to not mislead some innocent fans who believe in everything they read on the Internet without questioning anything ;-) 

Think a bit on things and in their consequences before you post this like that (and especially try to max that you can confirm the facts). The objective is to try not to induce people into error ;-)
