I'm loving this drama so much. :D
Regarding Wan and the Sunbae... Wan is so adorable, although a bit immature and so jealous~ Not the perfect man, for sure - even if he tries to be. There's a bit of creeper in him, too... But then, on the other hand, Tae Yoon is really turning out to be a great boss with a cute personality. What's not to love? I wouldn't mind Joo Yeon romancing both of them, lol. (But of course, she must be with Wan in the end. Otherwise, dramaland would be, like, broken.)
