Does anyone know this shoujo manga where it was the female protagonist’s birthday and she was supposed to celebrate it with her boyfriend however, when she went to the convenience store where her boyfriend was working, she found him kissing his own colleague. I remember this manga was heartbreaking because i think when she was meeting new people, it always didn’t work out between them even though it seemed like they were perfect for each other.

Any manga/stories about chasing one’s dream? Or just about someone who has dreams/goals in life that suffers from hardship and experience tragedies before getting the there.
