Unfortunately I agree with everyone regarding that female lead and I hope screenwriters/writers/directors take that in consideration. We are sick of these roles as viewers and readers. It is no longer interesting. The sister’s role played by Hee Jin is all the craziness we needed to entertain us. This reminds me of Itaewon C and most of all hated Soo-A i have considered dropping because of her many times but I live Park SeoJoon). Anyway This has nothing to do with Hong Su Zu’s acting ; that’s a subject for another day?.
