Hmmm, so there’s an emotionally stunted woman with black hair who doesn’t know how to relate to others because of a hyperfixation on her sister after an accident. She has a best friend who’s secretly been in love with the woman for years but was too afraid to confess, but suddenly feels compelled to state her feelings after she sees a new woman with pinkish orange hair (who has never fallen in love and thinks she can’t until she meets the black haired woman) getting closer to the mc, and makes the friend realize the black haired woman is changing with or without her…
Gosh where have I seen this plot before? Jk, in all seriousness I love the series but wow do the parallels keep piling on.
