I suspect that the author ended up wanting to develop the couple to introduce them to each other's families, friends, both being in an openly gay relationship, etc. They decided that it wouldn't end with the typical "happily ever after" where they're hiding from family and friends and we never get to see them interacting with their surroundings as a couple.
I'm so excited I hope Jaehyuk stands his ground, since he was considering introducing Garam to his parents at one point. I hope Garam doesn't go through another heartbreak, it'd throw all of Jaehyuk's progress out the window.

The dad is not the issue, it’s pretty apparent from what we’ve seen of him that he’s very supportive of Jaehyuk. The mom is where my worry lies. Since it’s not ending in season 3 as most of us thought, that could mean there’s a possibility that there would be some serious angst in season 4 regarding Jaehyuk’s new sexual preference and whether the mom accepts him and Garam. At least if it were ending in season 3, there was a high likelihood that the story was gonna wrap up in a neat little bow with everyone’s happiness. Now, that we have to wait, I feel like they’re gonna drag it out and give us unnecessary heart palpitations with season 4!!! I’ll take it though. We’re getting more of our favourites!!!

So so happy with the new season coming! I wasn't ready to say goodbye to them nor to you guys I am expecting a serious mess for next season maybe Garam meeting the parents and feeling so bad about the mom's reaction that he would take his distance and ask for a break-up pretending he doesn't like Jaehuyk anymore :,( And y'all please don't come at me for this but I truly miss a desperate and heartbroken Jaehuyk xD I love how crazy he becomes whenever Garam pushes him away! We had an amazing lovey dovey S3 and it's time for a big ass drama and then the best reconciliation ever!
- Garam and Jaehyuk are at the bathroom getting ready for the day. Garam is gonna buy Jaehyuk's present while Jaehyuk will visit the hospital to get his stitches removed. Jaehyuk doesn't want to be away from Garam. He gets turned on and eats Garam's ass.
- Garam sees a couple with rings and gets excited to buy Jaehyuk's gift. He arrived at a jewelry shop and the saleslady assumed he's getting wedding rings since his budget was quite high. Garam says it's just a couple ring. He included the amount of the settlement in his budget so it increased (am assuming he wants to repay Jaehyuk this way). He thinks that it's the first time he's spending so much money aside from his tuition, but he doesn't feel bad about spending it because it's for Jaehyuk. He even imagines Jaehyuk being happy to receive the gift.
- Jaehyuk got back from the hospital and as expected, it left a scar on his eyebrow. He thinks Garam will be sad about it so he'll prepare a delicious meal for him.
- Someone knocks loudly at the door. Jaehyuk gets annoyed. He opens the door, asking who it is, but he's shocked to see that it's his parents. His mom asks him, "Yoon Jaehyuk, have you really gone as far as to mess around with men now?"
- To be continued in Season 4
