Jisoo Kim, a well-known famous daughter of one of the richest business man in South Korea. She was a top student in her class. She's good in everything. Her father wants her to study all about busines but Jisoo never wanted it. She wants to be a doctor and save lives. She promised to herself that she'll be one of the best doctors in South Korea. She wants this to happen because of her Mom that died when she was still young. Her Dad can't do anything about it, so he agreed with what Jisoo wants and supported her. Jisoo is not taking her residency in one of the biggest hospital in South Korea. Before going to work, she loves to go to her favorite coffee shop. She became lowkey of her profile. Some of her friends know about her background as a rich kid but she tried to hide it to everyone. She also loves to take a morning walk, it's her own belief that it's the best exercise for her. Not until she bumped into a blonde woman that she will never expect to be a part of her life. On the other hand, Lisa was running very late because she overslept again. She's taking 2 or 3 jobs in a day just to make enough living for her and for her nephew whom he adopted because her older sister left his son to her. She promised to be back but few years had passed, no trace of her sister anymore. She quickly wore her uniform and took her jacket and run. She just kept on running until she bumped into a small brunette. She cursed because of a coffee that was splashed to her. Not until both of their eyes met, there's something. What will happen if Jisoo tries to look for her? Is she only want to say sorry because of the coffee or she wants to know more about Lisa?
