the blonde wanted to be depended on, to be needed, the blonde wanted to be relied on by the insecure dark haired and as they started going out, the dark haired may have thought that she needs to change, needs to become better, suitable, worthy for the blonde despite knowing she doesnt have to, and that impacted blonde the wrong way maybe because she wanted the dark haired to continue being same insecure, helpless girl, since if the dark haired stay the same she would rely on the blonde.
it's kinda how i interpret this one shot and i hope i conveyed it well.
breaking up wasn't the best solution, but maybe the blonde did that because she felt that she isn't needed anymore since the dark haired is doing better.
the blonde may have some problem in her home like being labeled useless or stuffs and the dark haired relying on her may have filled whatever needs fulfilment in her, and since the dark haired is doing better she felt like she isn't needed anymore, and therefore broke up with her so that she won't be hurt furthermore (by what i mean by hurt is that since she'll become 'useless'
and not 'needed' to the dark haired and thus maybe the dark haired will point this out to the blonde [therefore, this could is advance thinking]) so the blonde run away afraid of getting hurt and instead hurting the dark haired.
aaaaaaaaa do note that this is all just speculation and my thoughts on this oneshot also sorry for going around in circles ༎‿༎

the characters never apologize for the assault, and jaerim even if he almost got sexually assaulted ( i used almost since the author didn't show any explicit) jaerim doesn't care about that terror, especially from yuri when he almost got assaulted it really bothered me how jaerim was unborthered by it and in heeno and aerik's relationship (fuck don't know how to spell his name) i sort of want to know if they discussed about the past (since it's never shown in the series) i mean if it's me i won't say it either because i would be scared about getting dump again so i sort of relate to aerik even if it looks cowardly.
dunno and the former pres. their relationship is toxic and i kinda feel bad about the ex pres, he tries so hard to impress and get dunno while dunno doesn't want to be of anyone's belonging well anyways, i hope they find their happiness (though this is fiction)
furthermore, i loved this series it made me tear up and at first i didn't like the artstyle since it's very novel for me but after continuesly reading the series, I've come to grow fond of the artstyle, it's aesthetic and the way how it's color.
i relate to dong gyung(?) i don't remember his name but that dude with a burnt scar on his left side of the face, i relate to him. I'm self cautious of everyone around me though sometimes i don't if I'm surrounded with my friends.
anyways, there's also a sequel for that gray haired dude! the title is called INCORRIGIBLE if you don't know!.
so short yet very thought provoking makes me realized the same as everyone that we are doing it (like going to a prestigious school, well respected job) because the others are doing it too, not for ourselves but for the others even if we hate it.
never having the freedom to do what we actually want because we are too busy doing what the others are doing, too busy chasing what other's are chasing.
really love this mangaka, fully expressing depression.
