How come everyone is an ass in this manhwa except Inwoo

How is Jiho an ass? Tf. There are so many characters who are good.

jiho is insensitive af. he knew inwoo was on bad terms with his mom but he still took him to see his mom without even him informing about it. im sorry but there is certain line one shouldn't cross even if youre in a relationship and thinking better of your s/o.
also I know there are many characters who are good. for example jiho's mom and sister. It was just a figure of speech
