so kan-chan is abusive, but convenient for yumi, yumi is hung up with mayama, and mayama is wishy washy or something? idunno, can't really relate well with mayama. kan-chan and yumi are using each other, and kan-chan is hella abusive while yumi is emotionally unavailable; therefore, the relationship was toxic.
yumi was physically abused, though i feel like he let it happen for some reason. don't get me wrong, kan-chan's abuse is inexcusable. it's like yumi is doing self-harm yaknow. letting his life be wreck for a reason.
since we established that kan-chan is abusive and downright toxic on how he treated yumi, i'm going to say something that people might not agree with. yumi is a terrible partner imho. i read the prequel after this, and nothing changed, in fact, it solidified my opinion. yumi isn't reliable, and is still hung up with mayama. i can't help but think that yumi could've treated kan-chan better before the abuse happened. when asked about the phone, he raised his voice saying "don't touch it". he didn't even bother to help kan-chan financially despite knowing how kan-chan's situation.(okay let's recognize his effort to discuss switching jobs for kan-chan, but yumi could've moved in to save expenses, he is already relying on yan-chan sometimes since he keep being fickle with his jobs. it's like they are fwb instead of boyfriends.) and i hate the fact that he can't decide for himself with regards to his relationship with kan-chan; kan-chan is the one who ended their relationship. but yeah i was irritated with yumi, i just don't think he cared enough for kan-chan throughout their relationship like a partner would. he really expected kan-chan to go back to his old self just like that. he just waited.
i can emotionally connect with yumi and kan-chan cause at some point i was also toxic. i had anger issues like kan-chan but have not hit anyone, rather i hit myself a lot whenever i can't control myself. i also felt like i have to carry everything despite going under stress (and my partner is manipulative in a way, even going as far as threatening with self-harm or with suicide whenever i try to break up with them; we were so toxic). some aspects from their relationship is analogous with my, just in different occasions but with the same person. i also settled in a situation where i wreck myself and life, where i know i can leave anytime but just stay to escape i guess, like yumi.
i'm happy for yumi, of course. i personally don't feel anything towards mayama, i don't think he's perfect or something, just meh. i like this story a lot. :)
edit: god i really love kan-chan and yumi's characters. i read the sequel, it is so beautiful. they both understand each other. kan-chan really knows how yumi will react if he apologize, so instead he kept their picture to remind himself everyday about what he has done. there was a part when yumi learned about kan-chan's smile, it was so good. so in the sequel, yumi stated that he just waited, he also acknowledged that he was all about kan-chan smile and that he was still into mayama then. the sequel is all about second chances, it doesn't justify the abuse at all.

i'd rather choose yukinara than that shitty butler. i'm crying so hard reading this, specially when that fcking butler-- i especially cried when he let that damned sensei r*pe him. that mail man really do be a snake. i feel betrayed by that bastard of a nanny. i hope they die, both that nanny and the butler. please give my bois and girl the best happy ending, i hope they heal.
i know it might seem biased but i can't really feel sorry for both seme. the supposed issue for the first couple is just the lack of verbal expression from the uke, while for the second couple is the seme's violence (i don't get why it's suddenly the uke's fault. the impression i'm getting from them is that they already resolved the boob issue, and that the uke lost attraction after getting serious with the seme.) after having unnecessary violence and arguements, the issues are still not solved.
