the yandere was being confronted by the MC and his friends, the MC cornered her attempting to kill her once and for all but she took a boxcutter hidden in her clothes to cut the rope that tied her and attempting to attack MC's former crippled girlfried, but the MC is able to prevent it resulting in the yandere dying due to a cut on her neck. Time skip years later and we found out that MC and his former crippled girlfriend has married and she's being pregnant and they got a letter sent by the yandere girl (which somehow sent with a deliberate delay) to talk with the MC about her feeling. The yandere girl apparently survived the ordeal and being imprisoned but she ultimately commited suicide while writing "I love you" with her own blood on the prison cell's walls
