HP: James Potter's Twin Sister

[Ravenclaw heroine] [Written interspersed between children and parent generations] [Basically friendly to the original characters] [ooc apology] Seraphina Euphemia Flemond - James Potter's twin sister, three minutes older than him. Seraphina never thought she could wake up before she was de-petrified. At that time, she had already sent letters to prepare for her death, not knowing that she would miss the deaths of James and Lily. From 1976 to 1993, she unexpectedly woke up and saw a black-haired boy riding a broom outside the window. Serafina, who knew nothing at the time, thought she had finally gone crazy - after all, the child looked like a young James, but had Lily's eyes. ———— "It's like a curse that only one twin will survive, isn't it?" [Main cb Xiang Wei's heartthrob] [cp: Serafina Flemond × Regulus Black Deputy CP: GGAD, Zhan Li, Ha Jin (may include Dog Wolf)] ps. Sijiao, Sirius, Remus, and Peter all have no cp-oriented feelings for the protagonist. Note that they don't. Pps. There are relatively few love lines due to well-known reasons.
