Uhm... I read the novel and I'm uncomfortable reading this because the manhwa make it look they are so in love and it's always fun and cheesy times, BUT in the novel Lee knows he can't walk away from Caesar cuz he will hunt him forever so he just stays with him not because he loves him, but because he doesn't have other options (and Caesar is a crazy psycophat). Aditional Lee really REALLY was traumatised from that time Caesar shot him and ra** him multiple times... that's why Lee is reclutant to marriage, cuz he does not love Caesar, Lee just resigned to live with him and wait for Caesar to die so he can be free. Lee gave up freedom and everything cuz he knows Caesar will not let him go without kill him or hurt him
Sorry for my English but there is so much I wanted to say cuz this story is sad and dark, not funny or cheesy like manhwa.
