Hi, everyone! I came across this manga a few months ago and I just can't remember the title (shoujo most probably). It's about a girl who walks under the umbrella on a rainy day after getting fired by the office. Her mother has depression and sort of emotionally abusive due to her loss of husband and her younger sister. Um, she meets a young woman, who asks her to take care of his brother, who has quit playing the piano.. That's all I remember.
If you guys can remember it, I'd appreciate it
Thank you!!

im not sure it might be nodame cantabile
