Tamara has been described as ambitious and somewhat cunning... for all the right reasons. Instead of using her ambition to her own benefits, she uses it to fuel her diplomatic passion. It is her drive to see a fair diplomatic compromise, and nothing short of it. From the amount of connections she's made over her time already, one could say she was born to be a diplomat. She denies all allegations of such; she made herself into one, because people aren't born with a given passion (admittedly, that is part of her life motto). Such drive gave her success in her time with the South Korean Ministry of Magic.
Tamara admittedly values every connection she makes, despite having been anti-social most of her life. On business, Tamara would be happy to talk about whatever is being discussed, but she's not the most social person outside of that. If you address her, she'll still present her full attention, but don't expect an incredibly long conversation, because Tamara is not fond of dragging conversations, and she'll cut it off if there is no further way to continue. Now, with a trick or two, it's possible to sway her otherwise, but it takes a lot of conversational maneuvering to achieve this.
Within however, Tamara has a deep fear of being rejected, of not meeting expectations. It stemmed from having so much go right in your life that... you don't want anything to not be up to par. Sure, she had her moments of failure every now and then... but those are insignificant, and didn't do much to change who she is. She firmly believes that no one can be incredibly successful without multiple failures in life... so she's afraid of when that time will come for her, because it will, some day.
How Kim Sol-Mi and Song Nam-Seon met is very complicated. Considering their circumstances, them getting together, much less having a child shouldn't have happened. But it did, and Song Tam-Hee was the result of this. Except, Tam-Hee would grow up with a single mother, for her father wasn't very keen on staying with her mother.
You see, Kim Sol-Mi was just your average small town Korean lady. She grew up in a middle-class family, albeit a wizarding one at that. Sol-Mi was a Half-Blood witch, who around the time in question, was only a recent graduate from Mahoutokoro. Nam-Seon on the other hand, oh, he was a rich man. He had recently inherited his father's tech startup, and things were perfect for him (yes, he's a Muggle). The two met on accident, and here's how; Sol-Mi was a waitress at a restaurant in Seoul, and Nam-Seon was only going there because he and a business friend had agreed to a chat over some nice dinner. Nam-Seon wasn't quite paying attention and he bumped into Sol-Mi. Nothing was spilled or anything, thank goodness, but it was awkward.
Nam-Seon ended up staying around a little longer so that he had a proper chance to apologize, but Sol-Mi had already forgiven him. They had a small chat, and Nam-Seon offered to take Sol-Mi to her home, which she gladly accepted. This chat would soon enough lead into a date, and one turned into two and so on and so forth, until Sol-Mi ended up pregnant. Nam-Seon supported her as much as he could, but he wasn't there as much as he and Sol-Mi would have liked. He was however there for Tam-Hee's birth, and he couldn't be happier.
The first few years of Tam-Hee's life were pretty normal, until Sol-Mi's secret was spilled. Not very willing to accept the fact, Nam-Seon tried to do something... but he will never remember a thing, since he and Sol-Mi were visited by Obliviators from the South Korean Ministry of Magic. Sol-Mi was warned, but not punished, since it was accidental, and the damage was very little. With all her respect, Sol-Mi chose to move with a young Tam-Hee to England. In time, Tam-Hee would be given the English name of Tamara, with her Korean given name becoming her middle name.
Tamara's magical sign came when she was 7 years old. It was a slow evening at the time, until the front door mysteriously opened. Tamara closed it and locked it again, shrugging it off as if it were nothing, because that is what it essentially was. She did tell her mother about it the next day, and that much due explanation about Tamara's magical blood came.
In time, Tamara would begin schooling in Hogwarts. She was sorted into Slytherin, an odd choice, but it will come to fit her as she grew older. For a Slytherin, she was admittedly one of the better students in her classes. She wasn't the most social person, as evidently shown by the fact that she kept few friends, and fewer more best friends. She was a lone wolf most of her time in school, but she did succeed nonetheless.
After graduating, Tamara spent a little time travelling the world. During her travels, she had happened to grow quite fond of the differences many nations had, yet, time and time again, she found similar setbacks to it all, and it'd be from this observation that she'd gain an interest in working in an international department. When she returned to Seoul, she soon found herself applying for their Department of International Magical Cooperation, and was accepted. She started as the PA of the Head of the Department, and she did a lot in the five years she worked in that position. She worked closely with the entirety of the department as well as the Korean ICW representatives, to ensure that her country was more involved. She often traveled alongside the Korean ICW representatives, more often than not as a task that she was given.
She had made many connections, and her work didn't end when she transferred over to IMOL for South Korea. She had grown a certain fondness of what she did, so it was without doubt that she wouldn't quit for years to come. But in time, she decided it'd be best to reunite with her mother, who hasn't seen her in so long. So she requested permanent leave, and was granted it. She then moved back to Britain, and is now looking into pursuing a position in the DIMC of the British Ministry of Magic, with nothing less of a keen eye.
