Oh My Ghost
tvN dramas usually don't disappoint, and I don't thing I'm going too far in saying that tvN dramas have been important in shaping the landscape of Kdramas in recent years. I have loved almost every tvN dramas I've watched so far but the following dramas are the ones that have stayed with me for a really long time/have affected me deeply/I really enjoyed:
