I guess u didnt know that Kang had seggs with many people when the uke left him and that he only tried once looking for uke(once was when he only check the grandmas house thats it) he was addicted to drugs when he found out that he cant find the person that marked him so he use seggs again and drugs until his sister helped him
Read the novel and u will understand "Our" frustraion
He also blaming moochan for distrusting uke like come on he didnt even had faith in our uke
Right! Like I said he made mistakes. I don't really like the seme because of what the uke went through because of him plus it's not right to blame anyone for your mistakes which is why people who committed sins have to go reflect and redeem themselves. Also, this is just a novel. In reality, I know a lot of people which is really worst than the seme but their partners forgive them which is really aggravating to see because in my POV I don't see why people continue to have relationship with those kind of peeps. I guess my point is let's just give him the benefit of the doubt and see if he really will changed. For me it's not important if they end up together or not as long the uke and the child will have everything that they deserve to have. I don't care about the seme tbh, for me he's just part of the plot.
In reality, no one's perfect everyone makes mistakes. It's really impossible for someone to be the ideal person that everybody wants. I guess what's important is that the one who made a mistake own it up, repent and correct the mistakes.
