Regression Series (Went back to the past)

FL is adopted and used by her adopted family only to make her drink poison herself at the end. She then regressed back to the time where the "real princess" came back.

Translation is meh, currently waiting for better and more chapters...

MC is working in the entertainment field who regressed after un-aliving himself from his regret of not taking care of his dead daughter. Now all he wants is to make his daughter happy and support her in everything she wants to do. (Daughter is actually a music genius btw)

ML is a struggling modern day person who wake up as a Prince and the Brother of the King of Joseon who was later known as a tyrant. To protect his wife he sets out to stop events from happening and aids his brother. Ending is 100/100 for me, love how they see each other again in the modern era (つ≧▽≦)つ♡
