В интернете сегодня прочитала о том, что все-таки треугольник будет. Не знаю, насколько правдива информация, потому что, насколько я поняла, это просто мнение одного человека:
Moon will have romantic story threads with both leading men, because this is K-drama, where nobody can get a job done without falling in love first. That means lots of angsty moments for our sharp and skilled assistant professor character played by Joo Sang-wook, whose affection for the heroine goes unrequited. Poor guy. At least he’ll have his brilliance and his looks to fall back on. Meanwhile, she’ll find her feelings increasingly stirring for Joo-won, the warm-hearted and “unique” resident with whom she’ll share a “sweet loveline.”
