Anyways, this is just my own opinion.. I was liking what they are having but now, I dont know what's gotten into Dojun...
I can see you points, but like - isn't it hard to let go of habits? They've only been together for a short while and it seems like Dojun never had a seriously relationship before Tae Seok and that hyung might have been his first 'love'. After so long feeling guilty towards his mom and brother, I don't think he realizes the instinctual habit he has of stepping away. Which I agree is pretty bad, but I personally love him, because we get to see his thoughts and inner workings of why he feels compelled to do what he does, and the letter part and facing and admitjng his regret immediately is a great sign of maturity. Also, I guess I don't place much blame on him, or have a lor of aympathy for tae Seok, because Dojun did warn him before accepting his advances - that he doesnt have much self esteem and he's always questioning himself, yet tae seok still pursued him and loves him - so I think overall they'll be okay. Maybe cry a little and hands might get thrown. It feels like an unfair situation, but taeseok is a grown man and made the decision to go after Dojun despite warnings, and I personally think Dojun deserves that level of love and affection, and as we've seen in previous chapters, he has the capabilities and want to return those affections back, he's just held back by his lack of self confidence - hopefully he gets the gusto and kick this twinkassbitch into the yesteryear because the only way I'm gonna be satisfied is one of them beating his ass up and out of this manhwa.
Im kinda pissed at dojun though, the moment his "hyung" came back he suddenly acts like tae dont even exist. As much as I hate the pale bitch, I gotta say he should said those so that Jun would wake up from reality that he has Tae!! Not being tied up still from that Hyung he likes to the point of having some mental breakdown. Like, I feel really bad at Tae, he really like dojun so much to the point that he'll understand what dojun's decision and even fired that pale bitch when he step above boundaries, but dojun? Suddenly his feeling sick from a mere words of his "Hyung"
