The Boy Next Door

Ji Jae and Gyu Tae are next door neighbours and are frequently crossing paths with each other. After several promised drinks, they finally meet up for an awkward drink until they meet Min Ah, which is personally connected to both of them. (Source: TVMAZE)

When Ji Jae falls down in his bathroom, he requests Gyu Tae to call 911. Gyu Tae, however, is stuck in his own bathroom as his door won't be opening. (Source: TVMAZE)
