Honestly, Jaehyuk worked on himself amazingly. He changed a lot for Garam and I think Garam needs to see and appreciate that or else things are gonna get ugly real fast for them. Jaehyuk really loves and has outdone himself many times for Garam but Garam has been taking everything for granted. And while I am aware that he's had previous sad incidents, I think he ought to trust Jaehyuk more. On this particular one too. He already knows that he was wrong before he even got home and he knows it himself that he's only making excuses because if he said something about it earlier, Jaehyuk would have set everything aside to celebrate it for him. That's how much he loves him.
On another note, I hope this only lasts for one chapter. They're quite adept in communication after they fought compared to other BLs. I hope it remains that way. :D
It's already up to chapter 83 in raws, methinks.
