After reading 10 chapters, I'm getting seriously annoyed.
The main character. Gets hurt or sick. In every damn chapter.
Seriously, he is like some annoying shoujo heroine who just keeps getting in trouble, getting hurt, fainting etc. so other characters have to save her/worry over her... Add to this that the guy has a huge emotional trauma because of the past incident and used to have a pretty bad asthma (as shown in flashbacks, oh joy, even more of poor!Takayama). Sorry, but I can't feel sorry for him. This is just annoying and ridiculous. His chara design/hair doesn't help the impression that he is an annoying girl. He supposedly is strong (a good fighter, somewhat "wild" etc.) which actually makes things even more stupid... Just admit he is an idiot who can't make two steps without breaking his leg or head, an idiot who doesn't know how to dress properly in Winter (so he can get a cold and others fussing over him again) and move on. Geez.
I'm not dropping this manga (yet) despite my annoyance and dislike for the main character because I like Azuma and Yuki (is he mentally unstable? kinda reminds me of Masao from Mars), I'm curious about their relationship. Not that I'm expecting much. Even if there is some Yuki-action, it's probably going to be interrupted by Takayama falling down the stairs. Or something.
**edit; ** After reading up to the 17th chapter, I'm raising my vote from 5 to 6,5. Takayama stopped getting hurt/sick all the freaking time, later Azuma gets more spotlight when it comes to this
(...motorbike accident... caughing up blood... falling down the stairs...)
, which makes the main character less annoying, but still spoils the story. I mean, all those accidents. Not only it's unrealistic, it also seems like a cheap trick to make things dramatic and the characters showing affection. There are many ways to get this result, many more interesting, unique ways. When a character gets a fever for the 5th time, I, as a reader, really don't get the "you poor thing!" feeling. It's just annoying and silly.
As for Yuki... He turned out to be different than I expected (he cannot be compared to Masao at all), but I really like him. His side story was cute and explained his reasoning and circumstances very well. What I dislike is that in the later chapters there no longer is Yuki in the story, the roommates changed, new characters are introducted (which I'm totally fine with), but so far I don't even know who Yuki shares with. Azuma is his idol, yet we don't get to see Yuki showing concern because of all the bad things happening to the guy "he's always watched". I have an impression that the only reason Yuki was in the story in the first place was to help develop Azuma/Takayama and make things dramatic. Okay, they are the main characters, it's their story... but, if Yuki suddenly gets "kicked out" because he is no longer needed, nevermind what we were told about his character before, then I'm sure I don't like this.
