Weren't there suppose to b a chapter about a sister that lost her baby brother due to car accident? Thats why there was an extra panel where the artist drew of a boy spirit flying towards heaven with the suicidal highschool girl spirit. I had this manga once when i was in middle school so when i read it here in mangago and the scenes are all jumbled up, i am very much confused haha
Nooooo whyyyyyyyy. This week my luck has only been meeting with deadly cliffhangersss!!!! Goddamnit! AND THIS CLIFFHANGER IS THE DEADLIEST AMONG ALL!!!
And now that i think about it, the 1st chapter is like a remake or like, a diff artist was drawing it so no wonder the 1st and 2nd chapter has the same plot. The original chapter starts from 2nd until the end chapter. But they missed out the original 2nd chapter about the twins' classmate that hate their relationship bcs she's still suffering from the lost of her baby brother due to car accident. It was sad when the brother's spirit would visit the sister in the classroom until the twins realized it.
You can check the missing chapter on Mangadex and i bought this manga a few years ago where the author mentioned that she actually won a competition or debuted using the first short. It was sort of a pitch to the story
