yeah in reality she and the black haired friend are truly awful but ehh what you can do? Yet I still can't get over that she cheated on him, left Shizuma and then has the gall to act as if she's still his best friend, like she didn't just utterly betray him, and literally no one including Shizuma has called her out? I wonder why the author did that.
Strangely enough, I think there's a somewhat realistic touch to it. Considering these two were dating for multiple years, I would say there's also a deep friendship between them - cheating or not (as bad as it is, of course), it's quite possible for them to stay friends despite that.
now that you say it, it sounds like a reason. although, rather than saying there is a deep friendship, i'd rather think it is a bond that happens just because they're in the same situation together. i feel like shizuma always emit that 'well whatever' aura around his friends? do i make sense? while that girl has no conscience around her surrounding. and it just shows how twisted her personality and how kind and weak shizuma's personality. idk i feel like what i type doesnt really convey what i wanna say lol
yeahh i got kinda really mad when i see the black haired dude being so quick to judge minato from his appearance, but didnt say anything about that girl cheating on shizuma. and he even blamed shizuma for 'being lonely to the point picking a bad company' and then at the last chapter he dares to say 'i'm concerned about who you hang out with because i'm your friend' ughh i feel like i'm mad for pointless thing tho
that girl is literally a psycho tbh. doesnt she know boundary? she doesnt respect shizumas privacy eh. and so nosey. and clingy. wow a lot more reason to dislike her.
also, she and the black haired friend are honestly toxic. ugh.
