Levi OVA (My version)

Levi Ackerman lives with Isabel and Furlan in an underground city, and initially Levi was wandering around because Levi was a little bored at home because Isabel and Furlan were having a silly fight, Levi's intention was just to get some fresh air, who knows, a wind might pass by and there were some thugs and Levi as usual easily broke through them, and continued again and suddenly someone seemed to be targeting Levi and Levi was shot from behind, and Levi fell and the person immediately left and you walked and found Levi who was weak and you didn't know each other at first and you approached Levi to help with whatever help you brought, whether cloth, clean mineral water, and some bandages, and you knelt down near Levi
