Yeah... People might not like the Taegu act, but in perspective for thug, it's actually good thing he do and show how he care for the boy..
While I don't like the romance aspect, he has done so much to support and help the MC and the couple NEEDED that push (they are both haunted by the brother). It's kind of trash that everyone just wants to throw Taegu away now that the MC and the ML have officially gotten together. Keep in mind, this chapter also shows us that Seo In hasn't even started setting boundaries with the people he regularly associates with which is only going to cause them issues going forward. The MC shouldn't be the one speaking for or setting boundaries for the ML, he needs to do that himself if we want to see any meaningful impact. The MC also has so few people he can rely on and get support from, so I don't want to see this taken from him especially since him and Seo In aren't fully open with each other yet.
Also unpopular opinion, while it was wrong for Taegu to share the file with Seo In; it needed to be done. Sorry not sorry. Love our MC but his anxious a** was never going to open up or share anything. And Seo In is a dumb blonde at heart (man is oblivious). We need Taegu to push the plot forward unfortunately because both MC and ML has let their trauma keep them from moving forward.
