1. Anemia
Serenity was diagnosed with anemia when she was 17. She takes iron supplements but sometimes forgets to take them. She has never really talked about her anemia, those close to her only learn about it because of her manager. When she goes out to eat with people if her manager has their number he will text saying Serenity needs to eat something that is iron rich.2. Her Allergy
Serenity has a strange allergy which is that she is allergic to medicine that is in certain bandages, plasters/ band-aids and blister plasters/ band-aids. She feels no pain but swells if any are applied to her.3. Her Mother
Serenity's mother left her when she was a child. It was about a year before she began her trainee period. No one knows how it affected Serenity not even those close to her. Serenity has hinted that she doesn't recognise her own mother from a recent photo she seen.4. Her S**cide Attempts
Serenity never talks about her darkest moments. No one knows just how many times she has tried to end it all. Only during one dark time did she reveal to Yuta, Jaehyun and Hazel just how many times she has tried while sobbing into Jaehyun's chest, the three agreed never to reveal or mention it to anyone and have stuck by it. (Hint: It was over 30 times)5. Self-defense
Serenity as well as all active artists in RMentertainment were given self-dense classes. Serenity has only shown Jaehyun once and when she had him pinned things took a turn....towards the more behind closed doors. Jaehyun is very weak for Serenity and her pinning him did things to him.
