Uke is severely depressed and suicidal mainly due to the death of his parents (seme is also depressed and suicidal due to his ex's death)
Uke currently has an abusive husband, seems to be regularly raped/SA'ed by him and others, and has other traumas that haven't been fully revealed yet
Uke is severely depressed as a puppet king whose sole purpose is to bear the White Tiger's heir and die. He also has an abusive relationship with 2nd ML
Uke is being physically/sexually abused by the 2nd ML and a lot of other men (his 'clients')
Uke was apparently (I can't get past ch.1 to confirm, this is so bad lmao) raped and confined by seme's father
Uke was raped/groomed by seme's father since he was a kid
Uke was a sex slave and was therefore constantly raped
The love of uke's life (the 2 MLs' father) suddenly died
Uke seems to have some sort of unknown trauma related to being gay (I'm guessing either SA or being bullied)
Uke gets almost gang-raped by order of the 2nd ML (the white-haired guy. Yup, the actual ML is the friend)
