am I the only one who didn't get it?! why the fuck they break up again??!! I don't get it....

I have to say I'm a little surprised some people don't understand this, I honestly think this is one of the best mangas with drama that isn't just for the sake of drama like I can actually believe the emotions of each character, like what motivates them you know? but anyway the root of the issue is that Jaeha is insecure. He doesn't think he's good enough for Eunho(?), he doesn't want to hurt him either and he's got the pressure of Eunhos family plus his failed past marriage and Eunho keeps pushing the marriage thing on him because one he's loved him since he was a child and two he's honestly unaware that Jaeha is feeling those things because he never tells him, he just went along with things up until now and then a wave of doubt hit him and he wants to end it before it's too late which is clearly unfair to Eunho but at the same time I can understand Jaehas reasoning I mean I would be hesitant to remarry after everything that occurred in his last marriage plus he wouldn't be marrying a woman this time and on top of that this is his childhood friend who hopelessly pined for him so I can see why he would be so reluctant and for me his realization isn't out of no where, it's actually really well written. He was enjoying the happiness and then his fear and doubt caught up to him and took him away from that moment. Hopefully that shed a little light for you, maybe try rereading the manga in one sitting if you can and you'll see exactly what I'm talking about, maybe lol :)

because the hyung is being a considerate ass again by running away. The Hyung thinks if Eunho is with him, Eunho can't have a real family and maybe disowns by his family. （￣へ￣）

for that consulting exist, it's not a reason to break up. it a reason to go to Psychologist. I get he stupid and insecure, but it not really a reason to break up...

yap I agree basically a considerate ass or just an ass XDDD whatever. if making a "family" was soo importent to him they could have just adobt a baby or a child XD do you know how many Orphans you have in this world???????

ohhhhh yeah. All those orphans need a lot of loves from parent/parents. isn't gender another matter? People really need to erase their mindset of being homophobic.
Anyway, that jackass hyung shouldn't give Eunho hope from the beginning, if he gotta fuck him up this bad. (╯°Д °)╯╧╧

I mean sure but I don't think they were "officially" dating so to ask Jaeha to go to counseling about this was probably out of the question. from your viewpoint I get what you're saying for these characters though that's a long shot

The story is set in Korea where gay marriage and gay adoption is illegal. Many people who have wanted to take the next step and get recognized officially can't because of the homophobic rules that precise over them. It's extremely complex and so heartbreaking to think that people can't do what they want in certain countries. So no, Eunho and Jaeha most likely won't have kids unless this version of Korea has it's rules bent

if they have super smart phones there is other Countries that do support gay marriage's and adobtion. just saying. so fuck Korea XD

from the character's point of view that know he have a problem, and he did know! then it his job to try and fix it and go to counseling!! if he can't even do that then he don't really love his partner! he just use him for sex.

To sum it up he's a coward... after he realizes all the hurt he put Eunho through he gives him hope, than tires it all away... I mean really who the fu%k takes someone on vacay for the first time to break up... but I also don't feel bad for Eunho because it's pathetic how pitiful he is... and don't worry he always go crawling back... That's the one thing that bugs me more than anything, because that's not love to me...
