Endless Transmigration: These Shitty Lives are Killing Me

Baek Ain is your typical lazy guy.He graduated from university at age 22 with a random degree he chose out of boredom and stayed single because fate decided so until that event happened."What? Where Am I??"After a horrible incident, Ain transmigrated to another world. Or precisely to be a villainous and mobs character.He died countless times because of the world's protagonists, gathering hatred toward them."What the fuck! What do you mean I stole your wife? I've been single since coming into this world!!""Hero, please save this world." A goddess is begging me to save her world from the Demon Lord."Wait... Begone thot! That Demon King is my younger sister from 69th Transmigration.""How dare you!"A beautiful heroine is hugging me from behind, wishing to accept her feelings."Shoo, Heroine! I don't need useless baggage with me. Side characters are better than you!"And so, Ain's journey began to end this shitty transmigration cycle.
