- Some English translations are misleading in a scene where Eun-mi throws a knife to the door with a water amulet. She was not pursuing her own revival (although she is a bit crazy, she's not a ghost), but was wishing for her daughter (Seong-ah) to be revived. The janitors were blocking her way when the fire broke out while Seong-ah was in the Home Economics room 3 years ago. This became Eun-mi's trauma, and this is why she hates the fire alarm sounds and the janitors so much.
- A person who called Ji-hyeon to the school can be either Na-yeong or Seung-ah. in the game, Seong-ah says that Na-yeong and So-yeong's voices are very hard to distinguish, and Ji-hyeon said that So-yeong called her to come school when So-yeong never called her.
- The ghost that is hanging from the noose in the second floor of the old building is Na-yeong. She continuously pops up in front of amulet areas to guide and help Hui-min.
- Foreigners who do not understand Korean and are using the English patch have a difficult time seeing the Tuberose ending, because of some English translation errors that are caused by cultural differences. You have to be nice to Seong-ah all the time to see her true ending, but there's a time where you have to choose between two seemingly negative answers and it gets confusing (something like 1. No vs. 2. I don't care). However, in Korea, you have to say yes to the negative question to say that you agree with the question.
- For example, let's say that someone asked you "Did you understand?" to see if you understood. Both Americans (and Europeans) and Koreans will say "Yes" to say "I understood", and "No" to say "I did not understand." However, if the question is asked in a negative way, "Didn't you understand?", then Americans will still say "Yes, I understood" or "No, I did NOT understand." But Koreans think that because the question was asked in a negative way, if you say yes, then it means that you agree with the question, thus it means that you did not understand. So Koreans would say "Yes, I did NOT understand", or "No, I understood". So, the kind answer to Seong-ah to the above question with 2 negatives choices would be No. So the choices were actually (1. No, I care about others vs. 2. I don't care, something like this).
- There are conversations you can hear in the last chapter of So-yeong's end (the labyrinth chapter) they are as follows:
- Phone conversation between Seong-ah and So-yeong. (Seong-ah says that it's really hard to distinguish So-yeong's voice from Na-yeong's voice. Seong-ah was close friend of Na-yeong, so she was friendly with So-yeong as well).
- Phone conversation between Seong-ah's mother and Na-yeong's mother (saying thanks to each other).
- Conversation between Seong-ah and Na-yeong (shows how close they were).
- Seong-ah, alone in the Home Economics room, looking for Na-yeong when the fire broke out. She continuously cries out for her mother and Na-yeong.
- Seong-ah's mother rushed to school, but the janitors won't let her go in. She continuously searches for Seong-ah and cries out her name.
- Seong-ah is crying out for her mother.
- Seong-ah (ghost) holds a grudge against Na-yeong.
- "Na-yeong, look at me. Can't you see me?"
- "When I was dying...where were you?"
- "Don't try to act sad. Don't act nice...I will make you feel me (laughs)."
- So-yeong tries to talk to Na-yeong, who is suffering alone in guilt.
- The panintings that are hanged on the walls in between classes in the Main Building are actually artworks drawn by fans for a competition Sonnori held before the release of the game, contestants were rewarded by full physical copies of the final game.
