[COMPLETE]
Shin Soora lives cloistered in her apartment due to a variety of diseases. Everything she does is online, which makes her into a really lonely young adult.

None of the other neighbors can really understand her, treating her like a weirdo. Except for Kim Seokjin, from the 401, who is in fact her therapist, and Jung Hoseok, from the 402, who helps her with everything he can, being her only "real" friend since almost forever.

But things start to take a turn and an unwanted change revolves in Soora's life when Min Yoongi moves to the apartment next to hers, the 301.
Will Shin Soo be able to overtake her traumas and win her battle against herself with the help of this new and unexpected friend?
