Taeju seriously needs better development. 
1. I'm glad he's having some self reflection but come on. You love him Taeju but it's just plain selfishness to keep Euihyun trapped for the sake of love. I honestly think they're a cute pair but I just can't with the toxicity. 
I hope Taeju comes to senses and gets rid of the debt and let go of the uke. Therefore it shows he really loves him and gives Euihyun some space and even a reason for Euihyun to develop some romantic feelings. However I doubt that's the direction it'll go to. I'm afraid Euihyun health will only decline. My predictions being, he thinks about taking his own life. In the trailer it had showed him standing by the sea, alone this time. And if that's the case, I beg for Taeju to save him just like he did on the first chapter but this time to actually show his love. 
Also the dad can f*** off lo
