Tokyo Revengers x Lookism crossover fanfic (TR x OC)

DISCLAIMER: I DO NOT OWN THE CHARACTERS OF LOOKISM OR TOKYO REVENGERS. JUST THIS IDEA AND MY OC! ALSO This is purely for entertainment purposes only.

So, not much is known about Daniel Park's family, only theories, so this will be based on the theory that Park Jinyoung is Daniel's and Johan's father. ALSO, my Oc is related to both Daniel and Takemichi.

Takemichi's mother is Park Ara's mother's sister. Takemichi's mother and Ara's mother sister both have blue eyes and blonde hair.

How is she related to Daniel and Johan? Well, she is their half sister. Her mother moved to South Korea, due to her work. She met Park Jinyoug while exploring, and they hit it off. One thing led to another then he left. She wasn't aware she was pregnant until it was too late. She moved to a rural town, and there she met Daniel's mom, whom also had a run in with Park Jinyoung. The two bonded and became friends, and so Seonhui invited Ara's mom Tsukki to her wedding to Park Sangcheol, as Tsukki had married a man named Park Jin Soo. Once both babies were born, they were raised as siblings and best friends. As they grew, their bond grew as well. To the point where they had two moms- Tsukki and Seonhui, and two fathers- Sangcheol and Jin Soo. They considered themselves twins, and did everything together. However, Ara was home sick from school. Her mother was at work, so her father Jin Soo was caring for her. She heard fighting, and quickly hid under her bed. She witnessed everything. Then a few years later when she was 17, her mother was killed. So, she ran away to Daniel's place. She knows his secret and helps him keep it.(I'm not doing every little thing in the manwha Lookism, so some things are made up)
