An educator is not an easy job - moreover, being an introverted person. Mina doesn't see herself as a good speaker, much more teaching people. Every trait that she had screamed that she is not suitable for the job. She started working as a lecturer at a local university in Korea after she had finished her study in the UK. Getting back to Korea was never a choice, but she doesn't have any say in that matter.

Being broken heart, getting back on her feet was no easy feat. Making new friends is difficult with her character, but she managed to pull through because of the grace of the people around her. Her everyday life was quite dull until she gotten involved with her students in many ways. 

Sana, a student of her, charming, lovely, with bubbly personality attracted her. Mina had been monitoring Sana for sometimes and she found out that Sana had been keeping her personas from others.

Chaeyeong, one of the students under Mina supervision gave her a very bad impression. A person with a bad attitude that ticks Mina off often labelled as off limits to her and she's been trying to do that - but seems can't get it done.

What will happen to Mina and the people around her? I'm not really sure yet, but still, please enjoy while it lasts.
