Progression

I'm with you. It's a huge improvement yet more people are vocal about their hate now that he's finally shown his dere dere side. People really see things differently. XP
Kenji is new to these things. after his past relationship that shook him, and it looks like he himself has yet to grasp everything yet. If anything i applaud his development here. There's a chance he might return to being the same ass as he was before in the future chapters but cmon, change in a person happens gradually. You can't expect him to be 90% dere dere at once.

having a bad past DOESNT give you a free pass to treat some one else like shit. and treating someone like shit, DOESNT mean that hes a tsundere. theres a fucking difference, youre just trying to justify his shitty behavior. "he's finally shown his dere dere side" and his 'cute' 'dere dere' that he has 'finally' shown, all of a sudden cancels out all the shitty things he has done?" "Kenji is new to these things" and what? is okay that he acts like a dick because hes 'new'? "after his past relationship that shook him, and it looks like he himself has yet to grasp everything yet" because he had a bad relationship, it means that its okay that he treats other people like scum? quit trying to excuse his behavior with all this bullshit ass excuses. pisses me off how you think its okay for anyone to be treated like crap, because of his past. its like me saying that its okay that my gf abuses me because she was abused before. smfh, see how fucking dumb you sound now? quit making excuses for something that cant be excused. all your comments of yours that ive seen so far is just you trying to justify him. i get that someone could change and shit, but thats not what youre saying at all, youre just giving excuses for his behavior.

your definition and my definition of 'lovely' is definitely not the same.

And that's okay.

Yep, you are right. An asshole is an asshole but that doesn't mean he should be one forever. Before anything else, let me remind you that people perceive things differently which is why I respect opinions that differ from mine. However it seems you understood my points wrongly. I am hoping for your open-mind. Humans are complicated creatures so your linear assumptions cannot exactly justify my point.

1. "his 'cute' 'dere dere' that he has 'finally' shown, all of a sudden cancels out all the shitty things he has done? Kenji is new to these things" and what? is okay that he acts like a dick because hes 'new'? "after his past relationship that shook him, and it looks like he himself has yet to grasp everything yet" because he had a bad relationship, it means that its okay that he treats other people like scum? "
-No, definitely not. and you won't find me saying "it's ok" to be an ass. Possibly it's my positive vibe that made you misinterpret my point. Why I'm positive about this is because of the possibility that he could really change to be a good version of himself someday. :)

2. "quit trying to excuse his behavior with all this bullshit ass excuses. pisses me off how you think its okay for anyone to be treated like crap, because of his past. "
-oh no, no, i never said it's ok because he had such a past. My point here is to try to understand where he's coming from and to appreciate the progress he made. he is an ass. sure, but i will not be the same ass who would consider him a lost cause especially not when i see hope in him to be good. Considering how he was in the previous chapters, him recognizing Yoshito's importance is a huge step and while that may be small for others, to him it's "new" therefore it's a big development. Don't get me wrong, if Kenji happens to be right in front of me and he goes on a fit, i will not hesitate to reprimand him myself. But because i -at some level- have an understanding oh him, i will be less overcame by emotions because if i ever were godknows what shit i could have done that could make everything worse.

3. "its like me saying that its okay that my gf abuses me because she was abused before. "
-Thank you for providing a scenario where I can further prove my point. First of all, it is obviously not ok if your gf is abusive, based on your example. Would you rather be the same ass as she is then? If I were in your shoes then I wouldn't, because i love my gf, so I'll try to understand her. Understanding does not mean to completely tolerate the abuse to the point where you'd just surrender and take it all. Understanding will provide me a more rational mindset so you can deal with the situation better. Because i love her, i want her to change for herself. I can guide her to understand herself better too and once she has, she'll have more idea on how to change herself. To alter the 'effect', you must find the 'root' first, right?

4. "smfh, see how fucking dumb you sound now?"
- Please exercise respect. I do not want to return this question to you.

5. "quit making excuses for something that cant be excused. all your comments of yours that ive seen so far is just you trying to justify him. i get that someone could change and shit, but thats not what youre saying at all, youre just giving excuses for his behavior."
-I am hoping at this stage you have either understood my point or at least understand the reality that we are seeing and we'd be dealing with this issue differently.

That's it! Thanks!
