that is because Naho was brought up to believe that his value as a person, his whole self-esteem depends on his beauty and when he is rejected by society his personality breaks down and he becomes depressed (it also happens with being smart, funny, or good at sports).
That is very common in the East, they are obsessive with facial aesthetics. What they don't understand is that beauty is subjective!!! ┑( ̄Д  ̄)┍

There's nothing wrong with liking mid looking characters cause most of us are average looking. Your standards are just too high that's all. And if depending on a sole person and having insecurities about yourself is 'a personality of a wet plant ' then you are most likely from other world and should be kept in a museum for others to see
Amongst all the yaoi I’ve read recently, naho is one annoying character. Why and how the parents kept showering him with “oh you’re so cute, the cutest boy in the world” is fcking weird, creepy, and the most bullshiet of all bullshiet. Like the other students say as well “he is average looking” and he really is. Not a memorable face, definitely not a cute uke
