I think this is how the drama is going to take place
The FL will die becuse of the poison and the ML will retrive here. But the catch is she'll loose her memories and fall in love with him. By the half or after 2 or 3 ep she'll regain her memories and the real plot starts from there ownwards (the love hatered relationship)
As an eldest daughter in the household i can somehow underatand Mi-rae's frustration. Even though my family is happy, if my dad gives my mom a hard time and leaves us to ourselves and comes back after years just becuse just has more money and wants to recline, I don't think that hatered for my dad leave completely even if i fogive him 🤧.
ALL THE MEN IN THE DRAMA ARE SPINELESS 💀
