Obsessive/possessive seme
Idk what if you can call their relationship love. It was just a twisted obsession, where the ml is blackmailed to be with his roommate. Any relationship outside of the roommate is considered as a threat.
The whole dynamic of their "relationship" felt wrong.
Toxic lover
The first chapters may seem like the seme is simply into BDSM. But towards the middle we realize his kink with BDSM is much darker and twisted. He was excited that his ex lover set himself on fire because of him. 😶
Yandere/possessive seme
The seme was seriously considering killing the ml. Like "If can't have you no will "
Obsessive/yandere seme
Made the uke believe he was an omega and locked him up when discovered the truth.
