(16:30) You're still texting me, though… You UNBLOCKED me! (16:31) I told you, I was just curious. (16:31) I'll block you again now. Have a nice life, whoever you are. (16:32) Wait

Levi was simply living his (boring) life when a sudden text from a mysterious number got him intrigued. He soon discovers that the stranger likes to live recklessly and is willing to sacrifice his heart for a life-threatening dream.

Warnings: references to drugs, violence.

Ragako is a developing, culturally rich tropical country famous for all the wrong reasons. It is home to some of the planet's most uncomfortably humid weather, it is blanketed by roughly 95% rainforest which is full of dangerous animals, as well as the civil war between the military and the jungle drug lords.

Eren is a young boy with aspirations of joining Ragako's military, much to his mother's displeasure. When his home town of Shiganshina is raided for supplies and he is taken hostage by the very jungle rebels he has dreamt of fighting, he's in for a world of trouble...

Warnings: violence, heavy angst, blood, gore, implied/referenced noncon, character death 

The Intern by Lutte

Armin was convinced that it was the opportunity of a lifetime, but Eren just saw it as just another chance to fail. Nothing good could possibly come out of an internship in a stuffy office at Survey Corporation. Eren would have been content to sit and watch the remainder of his senior year pass him by. However, after one elevator trip, Eren finds himself questioning everything he thought he knew about life and himself.
