it is toxic. cirrus used skylar's feelings for his friend to blackmail him and made skylar do the things he never really wanted to do. both of them were problematic. but just like what paskim explained about their dynamics, skylar wanted to forget his past/scars while cirrus resented his past/scars. (im sorry i cant accept skyrus slander, but i can acknowledge they have problems<3)
the blackmailing part literally reminded me of another manhwa but it was softer (didn't literally have any sex scenes) what was it? oh... it's Lost In The Clouds
