ZZZ's manga / #Career/Skill(55)

MC lived in happy noble family with parents, married older brother and his baby son and wife. They adopt OGFL who had divine powers and MC and OGFL are close as sisters. One day MC and OGFL come across a boy named Nix who had nowhere to go. OGFL decides to bring him to their home despite MC not wanting to bring him back as he seemed unsettling. Nix displays obsessive tendencies to OGFL and follows her everywhere. Turns out he's an evil priest who worships a dark God (something like that) and he wanted to take OGFL powers for his God. When he couldn't get her powers, he unleashed a dark magic that sacrificed everyone on MC land including MC family. MC survives with her baby nephew. OGFL seems to disappear. Nix was captured and sealed away by the temple in a dungeon for the tragedy. MC determined to survive and revive her family name for her nephew. Starts wine selling business and in 10 years revives family name and wealth. Unfortunately Nix escaped and kidnapped MC at an event in search of OGFL. MC gets put into a dungeon tower as hostage. While in dungeon tower MC dreams of book detailing her life and tragic ending. Apparently she never survived the attack on her home 10 years ago but OGFL used all her divine power to keep her alive. She also saved baby nephew and left him with MC. MC had forgotten this and started to remember. The reason Nix found her was because she has OGFLs divine power. She also saw that Nix would send parts of her body to lure OGFL and then kill her in front of OGFL. When she dies, OGFL would get her powers back and defeat Nix. Determined not to die and knowing she has divine power inside her from OGFL, MC uses that to attack the underlings and escape to an area with a sealed paladin named Norman.
