I agree :/ I definitely understand Garam on the fact that JH suddenly outing them is a no-no. While there is absolutely nothing that is shameful to have, society is a bitch and it will change how others react to them, specially with Korea being still so conservative. Not my that, JH pretty much just pushes forward with his actions without discussing it with his partner which ? brother, chill a bit and talk it first.
On the other, JH has gotten really far and tried to be supportive and understanding, a having Garam walk away instead of stay to talk it out was really such a slap to the face. thats not how relationship work. Garam is also too closed off and has a hard time expressing affection, which I get how an expressive JH could get insecure at his semi-rejections (like the ring thing)
I think they both have to try to meet in the middle and REALLY improve their communication ( ̄へ ̄)
But I have faith in them!

Actually tho, both of them do have a point. This is one of the rare times that I can't pick a side. Jaehyuk did try to understand Garam and made decision based on what he thinks is right, also it's his personality to idgaf and voice out what made him happy, be proud of everything. On the other hand, it's the opposite for Garam, he's always conscious of what other people think and it's his personality which is valid given what he went through. And same for Jaehyuk it can't be change overnight. That cool off also needed. BUT his constant thinking of the possibility of them breaking up is what puts me off. It just shows that Jaehyuk's feelings seems much deeper than his
