My theory right now is that In and Siam both had feelings for each other, but In was so repressed/struggled so much with internalized homophobia that he basically pushed Siam away and into the arms of Mol (since he was probably oblivious about Siam's feelings for him as well), and when Siam then felt like In didn't want him, and obviously getting together with a woman was "the right thing to do", he just got together with Mol. I could also imagine that she got pregnant pretty quickly which might have forced them to get married.

Really good! In my opinion it gets better each episode.

The two men never met before ep 1 where Wang is 19 (he turns 20 in ep 3) and In is around 40. It's a big age gap, but there's no grooming, so if that's your only concern then I recommend you give it a chance and watch ep 1.

you mean the two boys, yashiro and kenta? because yes, they do get a very happy ending :)

i thought the ending was happy and really good, but there is one character who doesn't get a happy ending. ask if you have any more questions :)

It's absolutely not queerbait. You should watch the show, you won't be disappointed (I also watched and disliked The Shipper)

from what i've read: yes
