Hidden Behind Her Mask (Kuroko No Basket Fanfiction)(Tetsuya Kuroko X Oc/Reader)

Please know that none of the characters' ages are the same as the anime. Since I don't wish to spoil it for others, it will only be a bit similar but, not entirely. The same goes with all of my other Anime fanfics.

Hanagasaku Eienni is a High School student in her First Year attending Serin High. Although she is a First Year, she is in advanced classes and also well liked among her peers. She is very attentive to those around her and does her best to help them as well. She always has a smile on her face no matter how much pain she is in. She doesn't like to burden other people with her problems but listens to theirs and try to help them. She never joined any clubs either but is really hardworking. When word gets out to the Basketball Team, they ask her to help and join them. She is reluctant at first but when she sees how they truly are and their bonds that they share, she decides to help them out in all of their needs.
