Siempre tuvo claro que llegaría a ser la dueña y ahora, años después, como directora, se siente a un paso de obtener todo por lo que ha estado luchando.No obstante, esta solitaria mujer a diario se debate entre continuar con el rígido y anticuado sistema educativo que tanto prestigio le dio al colegio en el pasado o abrirse a las nuevas ideas que traen maestros como Lucía y Santiago.
Dedicated and disciplined, Cristina is a workaholic. She started out as a substitute teacher at the Golding Institute, but always knew that would become the owner and now, years later, as director, she is one step closer. However, this lonely woman is torn between her daily dealings with the rigid and outdated education system that previously brought prestige to the school and new ideas that come from teachers like Lucy and James.
