The first chapters of this manga/anime let me thinking that sometimes we expect people to be perfect in every sense to be a good person
Why can't someone be superficial, interested mainly in tits and dishonest occasionally and still be a good person?
Sometimes we can't tolerate even a mistake of other people, we don't let them be selfish even once, and if they do and for some reason we say we forgive them, we never let it really go.
We make it so difficult that people have to wear a mask in one way or another to mask their flaws.
