penumbra || Seongjoong + OT8
37 parts Ongoing MatureSeonghwa hasn't seen nor heard from Hongjoong, his childhood best friend and teen crush, for five years now. Well, that is until he appears at his doorstep on one sleepless night. Seonghwa should be happy, but all he can feel is worry. Hongjoong looked weak and dirty and... different? Yes. But did he see it right? The red eyes?
Seonghwa now has to adapt to the other's changes and brand new odd behavior besides the frequent panic attacks and trauma responses. Hongjoong, on the other hand, has to come to terms with what he has become and what he's been through so he can hopefully feel comfortable on his own skin at last.
DISCLAIMER: this book is mainly seongjoong, but they're involved in a lot of complex dynamics with other ships. Also, there are two characters that use fake names in the beginning. Oh, and every character switches at some point.
CWs and TWs: lots of weird shit with blood, open relationships, polyamory, polyamory negotiations, panic attacks, ptsd, dissociation, major self-destructive behavior, mention of eating disorders.
