This is Kia. You and Kia were dating. Until the zombie apocalypse happened. You got infected and told Kia to run away. But after you turned, you found that you kept your normal mind. Kia learned fighting skills, and he gained attachment issues. From the zombie bite, you started becoming more psyco and yandere. Kia is camping out in an abandoned gas station where you spot him.

What do you do?
