WARNING: Major spoilers ahead for It's Okay to Not Be Okay! Don't read if you haven't seen the latest episodes yet.
In the latest episodes of It's Okay to Not Be Okay, we were able to see the mansion Ko Mun-yeong grew up in, also known as the "cursed castle" that her father built in the middle of a forest! Despite her dark past—which is connected to the mansion—Mun-yeong (Seo Ye Ji) chooses to stay in her old abandoned mansion in order to be close to Gang-tae (Kim Soo Hyun). The mansion is huge, imposing, a little run-down, and is honestly scary—especially at night!
Here's a fun fact: The house's exterior doesn't actually exist. Like a lot of Korean drama sets, it was built by an amazing production crew on the Sanida Cafe grounds, which is located at 109-128 Chilbong-ro, Hojeo-myeon, Wonju-si, Gangwon-do, South Korea.
According to the Sanida Cafe website, a gate was installed at the grounds' entrance and the doorway of the "mansion" was built on the premises. The huge mansion we see in the series? That's all CGI!
