For someone who rates everything 7 and up, something really has to downright terrible to get such a low score.
List of things that were awful in this manga (I dropped it after 22 chpaters)-
1) The female MC bases her decisions around the other Mc(her love interest) which just shows how delusional and weak she is as a character.
2) This manga has drama which is typical to any shojo manga (love triangle, trauma, childhood friend resurafces, yk what i mean) but it does an awful job using these elements in pushing the story forward.
3) All the characters are annoying as hell. The manga also does not do any justice to the side characters and they are just used as props to the story without any real value.
On a positive note the art is great and a handful of scenes are cute.
