i dont really remember but in this one manga, the MC was kinda given as a settlement to the seme because the MC's brother company was in a situation. the MC and seme fucked (not romanticised but kinda psychotic). when the seme finally thought he has control over the MC's life, the MC purposely towards a car outside the company's building and got hit. he gleefully died looking at the seme's face of terror
bruh i asked this question public hahha. but apparently i got the death wrong. its not a car accident sorry

i wish that the older would break free from his stockholm syndrome and commit suicide. just so that the younger brother will regret everything that he had done
