Rena has a goal - climbing the career ladder. Which is why, she started an apprenticeship at the famous company "CueCrafts". Rena doesn't mind romance, but right now, she isn't searching for a relationship, since she is focusing on one thing and one thing only. But apparently, the universe isn't on her side, since it's letting those two exact things collide together. Her time at the company starts with a "get-to-know trip", which is where she meets Tài. He is also a new apprentice, and the bright red hair of the vietnamese man drew her attention right away. Her whole trip gets turned upside down by this oddly familiar man.Rena wasn't always the luckiest girl, but this time, she will find out just how much luck she has left.
