Rendezvous 

After being beaten up by bullies, high school senior Yi-Yeon Kang wakes up from a coma, only to find the world in ruins from an alien invasion. The streets around him are littered and empty, with bullies out looking for their next prey. As he navigates this new world, despite being too weak, he is determined to find and save his friend Young-Lin. Between bullies, aliens and this post-apocalyptic reality, he'll do all he can to survive... and to bring down those out to get him. (Source: Tapas)
