I’m not sure, it depends but I don’t think I would love Youzen as much as I currently do if Bou was not the way he is now. Whatever Youzen isn’t, Taikoubou is, and so they really complement each other. Part of Youzen’s pitiful charm appeal to me is particularly because Bou is the stronger of the two. He raises Youzen up emotionally while keeping himself afloat on his own. Bou isn’t as emotionally reliant on Youzen as he is physically but the physical element is more easily substituted. Not to say Youzen isn’t needed but when the person you look towards doesn’t necessarily need you, that makes it all the more bitter. Like unrequited love but not quite :P… If Bou were less capable, I’d have less attachment towards Youzen. If that were the case, Youzen would be taking care of someone who deeply needed his help, but the case in reality is, Youzen is trying to take care of someone who is already capable enough and the thought of that alone gives me the butterflies (this is putting aside some personal development they go through together later on of course~).
If Youzen was the protagonist I think the story would’ve ended in one volume.
